ALLEGIANT TRAVEL COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of Allegiant Travel Company (the “Company”) and its majority-owned operating subsidiaries. The Company has no independent assets or operations, and all guarantees of the Company's publicly held debt are full and unconditional and joint and several. Any subsidiaries of the parent company other than the subsidiary guarantors are minor. ~~Investments in affiliates in which the Company’s ownership interest ranges from~~ 20 to 50 ~~percent and in which the Company has the ability to exercise significant influence over operating and financial policies are accounted for under the equity method.~~ All intercompany balances and transactions have been eliminated.

These unaudited consolidated financial statements reflect all normal recurring adjustments which management believes are necessary to present fairly the financial position, results of operations, and cash flows of the Company for the respective periods presented. Certain reclassifications have been made to prior year financial statements to conform to classifications used in the current year. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission for Form 10-Q. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company and notes thereto included in the annual report of the Company on Form 10-K for the year ended December 31, ~~2016,~~2017, filed with the Securities and Exchange Commission.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates.

Recent Accounting Pronouncements

In ~~May 2014,~~February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" intended to create a unified model to determine when and how revenue is recognized. Under this ASU and subsequently issued amendments, the core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. Under the new standard, revenue related to certain air-related ancillary fees directly related to ticket revenue, such as seat fees and baggage fees, will likely no longer be considered distinct performance obligations separate from passenger travel and as a result will be reclassified into scheduled service revenue. In addition, change fees previously recognized when incurred by the customer, will likely be recognized when air travel is provided and reclassified into scheduled service revenue.

The new standard is effective for annual and interim periods beginning after December 15, 2017, and the Company will adopt it effective January 1, 2018. The Company continues to evaluate the impact on its financial statements of adopting this new accounting standard and currently believes that adoption will have little effect on earnings, although the change in classification of certain air-related ancillary fees, as described above, is expected to be material.

~~In February 2016, the FASB~~ issued ASU 2016-02 related to leases. This standard will require leases with durations greater than twelve months to be recognized on the balance sheet as a lease liability and a corresponding right-of-use asset, and is effective for interim and annual reporting periods beginning after December 15, 2018 with early adoption permitted. The Company ~~is assessing~~will adopt this standard effective January 1, 2019. The Company has not completed the ~~impact~~assessment of this new ~~standard, and~~standard. The Company believes adoption ~~of this standard~~ will have a significant impact on ~~the~~its consolidated balance ~~sheets. However, adoption~~sheets but is not ~~currently~~ expected to significantly change the recognition, measurement or presentation of associated ~~expense~~expenses within the consolidated statements of income or cash flows.

Recently Adopted Standards

In August 2016, the FASB issued ASU 2016-15, which amends the guidance in Accounting Standards Codification ("ASC") 230 on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of the ASU is to reduce the diversity in practice that has resulted from the lack of consistency on this topic. The Company adopted this standard effective January 1, 2018. This standard was applied retrospectively, which resulted in the inclusion of restricted cash as shown in the beginning and ending balances of cash on the Consolidated Statements of Cash Flows. A reconciliation of cash, cash equivalents, and restricted cash from our Consolidated Statement of Cash Flows to the amounts reported within our Consolidated Balance Sheet is also included in a table below our Statement of Cash Flows.

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220)." This standard provides an option to reclassify stranded tax effects within accumulated other comprehensive income (loss) ("AOCI") to retained earnings. Stranded tax effects occur when a change in enacted tax rates is recorded in income from operations, even in situations in which the related income tax effects of items in accumulated other comprehensive income (loss) were originally recognized in AOCI. This standard is effective for interim and annual ~~and interim~~reporting periods beginning after December ~~15, 2017,~~31, 2018, and ~~the~~early adoption is permitted. The Company ~~will adopt it~~adopted this standard effective January 1, 2018. ~~Significant classification modifications~~Due to the adoption of this standard, $0.6 million was reclassified from AOCI to retained earnings as of March 31, 2018.

In 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), (the "New Revenue Standard"). Under this ASU and subsequently issued amendments, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received. Entities may use a full retrospective approach or report the

cumulative effect as of the date of adoption. We adopted this standard using the full retrospective transition method effective January 1, 2018 and recast prior year results as shown below.

Under the New Revenue Standard, revenue for all air-related ancillary fees that are directly related to ticket revenue, such as seat fees and baggage fees, are no longer considered distinct performance obligations separate from passenger travel and are reclassified into passenger revenue. These are deemed part of the single performance obligation of providing passenger transportation. While the adoption of the New Revenue Standard did not ~~currently~~have a significant effect on earnings, $154.7 million of air-related ancillary fees for the quarter ended March 31, 2018 are now classified as passenger revenue.

The adoption of the New Revenue Standard resulted in a net reduction to our air traffic liability at December 31, 2017 of $5.9 million. This change resulted from the recognition of breakage revenue on issuance for credit vouchers that are expected to expire unused. In addition, we now defer recognition of revenues for fees associated with flight changes or cancellations rather than recognizing at the time the fee is incurred. The Company already recognizes revenue from the Co-brand credit card program on the deferral method.

The Company has a significant contract with Bank of America to issue The Allegiant World Mastercard® in which points are earned and awarded to cardholders in exchange for consideration received under an agreement with a seven year scheduled duration expiring in 2023. Under this arrangement, the Company identified the following deliverables: travel points to be awarded (the travel component), use of the Company’s brand and access to its member lists, and certain other advertising and marketing elements (collectively the marketing component). Consideration received from the Company’s co-brand agreement is allocated between the two components based on the relative selling price of each deliverable. The Company applies a level of management judgment and estimation in determining the best estimate of selling price for each deliverable by considering multiple inputs and methods including, but not limited to, the redemption value of points awarded, discounted cash flows, brand value, volume discounts, published selling prices, number of points to be awarded and number of points to be redeemed.

See Note 2, "Revenue Recognition," for more information.

Note 2 — Revenue Recognition

Passenger Revenue

Passenger revenue is primarily composed of passenger ticket sales, credit voucher breakage, seat fees, baggage fees, and other travel-related services performed in conjunction with a passenger’s flight.



	Three Months Ended March 31,
	2018		2017
Scheduled service	$	238,520	$	214,263
Air-related ancillary charges	154,717		133,223
Co-brand redemption	3,534		350
Total passenger revenue	$	396,771	$	347,836

Scheduled service

Passenger tickets. We provide scheduled air transportation on limited-frequency, nonstop flights predominantly between under-served cities and popular leisure destinations. We record sales of passenger tickets to be flown by us in air traffic liability. Passenger revenue is recognized when we provide transportation or when ticket voucher breakage occurs.

We recognized $155.9 million in passenger revenue during the three months ended March 31, 2018 that was recorded in our air traffic liability balance of $204.3 million at December 31, 2017. We expect the remaining balance of the December 31, 2017 air traffic liability to be recognized during the remainder of 2018.

Credit voucher breakage. We estimate the value of vouchers that will expire unused and recognize revenue at the time the credit voucher is issued.

Air-related

Air-related revenue is primarily composed of services performed in conjunction with a passenger's flight including baggage fees, the use of the Company’s website to purchase scheduled service transportation, advance seat assignments, and other services. We recognize revenue for these services when the related transportation service is provided. Prior to the adoption of the New Revenue Standard, the majority of these fees were classified separately as Ancillary air-related charges.

Co-brand redemption

In relation to the travel component of the contract with Bank of America, the Company has a performance obligation to provide cardholders with points to be used for future travel award redemptions. Therefore, consideration received from Bank of America related to the travel component is deferred based on its relative selling price and is recognized into passenger revenue when the points are redeemed and the transportation is provided. See below for a discussion of the marketing component.



	Points liability
Balance at January 1, 2018	$	8,903
Points awarded	3,233
Points redeemed	(3,534		)
Balance at March 31, 2018	$	8,602

As of March 31, 2018, the amount of deferred revenue allocated to the co-branded credit card program is $8.6 million and is reflected in the Company's consolidated balance sheet with the short-term component in Accrued liabilities and the remainder in Other noncurrent liabilities. This is estimated to be recognized over the next two years.

Third Party Products

Third party products revenue is generated from the sale of hotel rooms, rental cars, ticket attractions and co-brand marketing revenue.

Revenue from the sale of hotel rooms, rental cars, and ticket attractions is recognized at the time the product is utilized, such as the time a purchased hotel room is occupied. The Company follows accounting standards for determining whether it is a principal or an agent in revenue arrangements to determine the amount of revenue to be recognized for each element of a bundled sale involving air-related charges and third party products in addition to airfare. Revenue from the sale of third party products is recorded net (treatment as an agent) of amounts paid to wholesale providers, travel agent commissions, and transaction costs.

Pursuant to the co-brand agreement with Bank of America, the Company has various performance obligations collectively referred to as the marketing component. These obligations consist of use of the Company’s brand and access to its member lists, and certain other advertising and marketing elements. The marketing component is recorded as third party products revenue in the period in which points are awarded to the credit card holders.

Fixed Fee Contract Revenue

Fixed fee contract revenue consists of agreements to provide charter service on a year-round and ad hoc basis. Fixed fee contract revenue is recognized when the transportation is provided.

Other Revenue

Other revenue is generated from leased aircraft, engines, and other miscellaneous sources. Lease revenue is recognized ratably over the lease term.

Accounts Receivable

Accounts receivable, reflected on the accompanying Consolidated Balance Sheet, primarily consist of amounts due from credit card companies associated with passenger revenue. These receivables are short-term, generally settled within a few days of sale. Bad debt expense, which occurs in the form of credit card chargebacks, was not material in any period presented.

Taxes and Fees

Various taxes and fees, assessed on the sale of tickets to customers, are collected by the Company serving as an agent, and remitted to taxing authorities. These taxes and fees are not included as revenue in the Company’s consolidated statements of income and are recorded as a liability until remitted to the appropriate taxing authority.

Secured Debt

During the three months ended March 31, 2018, the Company did not enter into any new loan agreements.

Senior Secured Revolving Credit Facility

In ~~January~~2015, the Company, through a wholly owned subsidiary, entered into a senior secured revolving credit facility under which it was entitled to borrow up to $56.0 million. As of December 31, 2017, the balance under this facility was $41.3 million, net of related costs, with five Airbus aircraft included in the collateral pool. In March 2018, the Company ~~borrowed $22.0~~paid off the remaining balance under this facility.

On March 30, 2018, the Company amended this facility and will now be able to borrow up to $81.0 million ~~under a loan agreement secured by two~~based on the value of Airbus A320 ~~series aircraft.~~Series aircraft which the Company may choose to place in the collateral pool. The facility has a term of 24 months. Any notes under the facility will bear interest at a floating rate based on LIBOR plus ~~1.70~~1.75 percent. An individual aircraft may remain in the collateral pool for up to two years. As of March 31, 2018, there was no balance on this credit facility.

General Unsecured Senior Notes

In June 2014, the Company completed an offering of $300.0 million aggregate principal amount of senior unsecured obligations (the "Notes") which will mature in July 2019. In December 2016, the Company completed an offering of an additional $150.0 million principal amount of these notes, which were issued at a price of 101.5 percent ~~and are~~of the principal amount, plus accrued interest from July 15, 2016. The Notes bear interest at a rate of 5.5 percent per year, payable in cash semi-annually, on January 15 and July 15 of each year.

The indenture pursuant to which the Notes were issued includes operating and financial restrictions on the Company. These restrictions limit or restrict, among other things, the Company’s ability and the ability of its restricted subsidiaries to (i) incur additional indebtedness; (ii) incur liens; (iii) make restricted payments (including paying dividends on, redeeming, repurchasing or retiring capital stock); (iv) make investments; and (v) consolidate, merge or sell all or substantially all of its assets. These covenants are subject to various exceptions and qualifications under the terms of the indenture. As of December 31, 2017 and also March 31, 2018, the Company exceeded the consolidated total leverage ratio limit, which could affect the ability to make restricted payments in future periods after exhaustion of various exceptions. However, we do not expect this to have any impact on the restricted payments we routinely make in the ordinary course of business. The calculation is made on a quarterly ~~installments through January 2022.~~basis based on the trailing 12 months.

Capital Leases

The Company has capital lease obligations related to aircraft, which significantly impacted our recognized assets and liabilities as of March 31, 2018, but did not result in any material cash receipts or cash payments during the quarter.

Note 45 — Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received by selling an asset or paid to transfer a liability in an orderly transaction between market participants.

Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 inputs that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Company uses the market approach valuation technique to determine fair value for investment securities. The assets classified as Level 1 consist of money market funds for which original cost approximates fair value. The assets classified as Level 2 consist of commercial paper, municipal debt securities, federal agency debt securities, US Treasury Bonds, and corporate debt securities, which are valued using quoted market prices or alternative pricing sources including transactions

involving identical or comparable assets and models utilizing market observable inputs. The Company has no investment securities classified as Level 3.

For those assets classified as Level 2 that are not in active markets, the Company obtains fair value from pricing sources using quoted market prices for identical or comparable instruments, and uses pricing models which include all significant observable inputs: maturity dates, issue dates, settlement dates, benchmark yields, reported trades, broker-dealer quotes, issue spreads, benchmark securities, bids, offers and other market related data. These inputs are observable or can be derived from, or corroborated by, observable market data for substantially the full term of the asset.

The fair value of the Company's derivative instrument is determined using standard valuation models. The significant inputs used in these models are readily available in public markets or can be derived from observable market transactions and therefore have been classified as Level 2. Inputs used in these standard valuation models for derivative instruments include the applicable exchange and interest rates.

The fair value of the Company’s publicly held long-term debt is determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets; therefore, the Company has categorized its publicly held debt as Level 2. The remaining debt agreements are not publicly held. The Company has determined the estimated fair value of these notes to be Level 3, as certain inputs used to determine the fair value of these agreements are unobservable and, therefore, could be sensitive to changes in inputs. The Company utilizes the discounted cash flow method to estimate the fair value of Level 3 debt.

~~Note 5 — Derivative Instruments~~

The Company entered into a foreign currency swap in order to mitigate the foreign currency exchange rate risk associated with the forecasted lease revenue from 12 Airbus A320 series aircraft leased to a European carrier until 2018. The Company uses a cash flow hedge to minimize the variability in cash flows of assets, liabilities and forecasted transactions caused by fluctuations in foreign currency exchange rates. For the three months ended March 31, 2017, the net change in fair value recorded in accumulated other comprehensive income related to an unrealized loss on the hedge was $0.2 million compared to $0.3 million for the three months ended March 31, 2016.

At inception, the Company formally designated and documented this financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the strategy for undertaking the hedge transaction. The Company also assessed whether the financial instrument used in the hedging transactions was effective at offsetting changes in either the fair values or cash flows of the related underlying exposures. This assessment is monitored on at least a quarterly basis, and the change in fair market value of any ineffective portion of a financial instrument would be immediately recognized into earnings. For each of the three months ended March 31, 2017 and March 31, 2016, the Company realized $0.3 million in gains from its cash flow hedge into Other revenue. As of March 31, 2017, the Company expects $0.7 million to be reclassified from Other comprehensive income into Other revenue within the next 12 months.

At March 31, 2017, the fair value of the Company's derivative instrument was $1.3 million compared to $1.7 million at December 31, 2016, and is reported in the Company's consolidated balance sheet within deposits and other assets. Refer to Note 4 - Fair Value Measurements for additional information related to the estimated fair value.

Note 6 — Shareholders’ Equity

The Company is authorized by the Board of Directors to acquire its stock through open market purchases under its share repurchase program. As repurchase authority is used, the Board of Directors has, to date, authorized additional expenditures for share repurchases.

~~Share~~

For the three months ended March 31, 2018, the Company had no open market share repurchases. For the three months ended March 31, 2017, open market share repurchases consisted of the ~~following during the periods indicated:~~following:


	Three Months Ended March 31,				Three Months Ended March 31,

(1) Share amounts shown above include only open market repurchases and do not include shares withheld from employees for tax withholding obligations related to restricted stock vestings.

During the three months ended March 31, ~~2017,~~2018, the Company declared and paid recurring cash dividends of $0.70 per share, or ~~$11.7~~$11.3 million.

Note 7 — Earnings per Share

Basic and diluted earnings per share are computed pursuant to the two-class method. Under this method, the Company attributes net income to two classes: common stock and unvested restricted stock. Unvested restricted stock awards granted to employees under the Company’s Long-Term Incentive Plan are considered participating securities as they receive non-forfeitable rights to cash dividends at the same rate as common stock.

Diluted net income per share is calculated using the more dilutive of the two methods. Under both methods, the exercise of employee stock options is assumed using the treasury stock method. The assumption of vesting of restricted stock, however, differs:


1.	Assume vesting of restricted stock using the treasury stock method.


2.	Assume unvested restricted stock awards are not vested, and allocate earnings to common shares and unvested restricted stock awards using the two-class method.

For the three months ended March 31, ~~2017,~~2018, the second method, which assumes unvested awards are not vested, was used in the computation because it was more dilutive than the first method.

The following table sets forth the computation of net income per share, on a basic and diluted basis, for the periods indicated (share count and dollar amounts other than per-share amounts in table are in thousands):

NETWORK

We use profitability management tools to manage capacity and route expansion through optimization of our flight schedule to, among other things, better match demand in certain markets. We continually adjust our network through the addition of new markets and routes, adjusting the frequencies into existing markets, and exiting under-performing markets, as we seek to achieve and maintain profitability on each route we serve.

Our operating network as of March 31, ~~2017~~2018 represents ~~a 20.1~~an 8.9 percent increase in the number of routes flown compared to March 31, ~~2016.~~2017. Our total number of origination cities and leisure destinations were 98 and 19 as of March 31, 2018, compared with 97 and 20 as of March 31, 2017. As of May 1, ~~2017,~~2018, we were selling ~~382~~419 routes.

TRENDS

~~We are~~In continuing with our fleet transition to an ~~all Airbus~~all-Airbus fleet, ~~and, as part of this plan, have reduced capacity growth for the summer months. We~~we added ~~three~~four Airbus A320 series aircraft to our operating fleet during the first quarter ~~2017 and are expecting 15~~of 2018. Airbus aircraft flew 72.4 percent of our scheduled service ASMs for the quarter, compared to 52.6 percent for the same time period in 2017. We expect 26 more Airbus A320 series aircraft to be placed in service by the end of ~~2017. This represents a 41.7 percent increase in operating Airbus over the next three quarters. We continue to focus on the purchase of Airbus A320 series aircraft to add to our operating fleet.~~2018.

~~Additionally,~~In conjunction with the fleet transition, we retired five MD-80 aircraft during the quarter and expect to retire ~~nine~~the remaining 32 MD-80 ~~aircraft, and our two remaining Boeing 757-200~~ aircraft by the end of 2018. Although the ~~year. Our scheduled~~number of aircraft in our fleet will decline by the end of the year with the retirement of all of our MD-80 ~~retirements could be accelerated if unexpected major maintenance were~~aircraft, we intend to ~~be needed.~~

~~Although~~continue to increase our capacity and network as we have higher utilization rates on our Airbus ~~aircraft are significantly more fuel efficient than our other fleet types, fuel costs in the long-term remain uncertain and cost volatility could materially affect our future operating expenses.~~fleet.

We have seen significant improvements in our operations. According to the most recent Department of Transportation (DOT) statistics, we ranked among the the top three airlines for having the lowest cancellation rates in the industry for both January and February 2018. We have company initiatives to engage every employee in the goal of improving operations. Additionally, we expect to gain operational efficiencies as we transition to an all Airbus fleet.

Our customer satisfaction has improved. Travel & Leisure Magazine recently announced we finished third in its 2017 American Customer Satisfaction Index of the American airline industry, ahead of all three legacy carriers. The magazine reported we had the highest jump in score from the prior year of all airlines in the report.

In April 2018, CBS aired a 60 Minutes segment critical of our safety and the FAA oversight of our operations. We believe the report was misleading, misrepresented our safety culture at that time and now, and mostly ignored the substantial improvement in the reliability of our operations since the events reported. In the wake of this segment, our rate of cancellations increased and bookings declined. Within a matter of a few weeks after the story aired, cancellations and bookings returned to more normal levels. Although we do not believe the impact of this story will have a material effect on our results of operations, it is not known whether there will be ~~adding~~any lingering effect on our business.

The continued roll out of our new revenue management system has had positive results. We have seen five consecutive months of year-over-year load factor improvements. Our overall scheduled service ~~into an additional medium-sized city, Louisville, Kentucky, starting in May~~load factor for the first quarter 2018 was 85.1 percent compared to 82.2 percent for the first quarter 2017.

As of March 31, ~~2017,~~2018, we were offering service on ~~101~~142 medium-sized city routes compared to 73101 as of the same date in ~~2016. Our East Coast presence also continues to grow, and we recently announced Destin, Florida as our newest base with seasonal service~~2017. We have 29 new routes expected to begin in ~~May 2017.~~

Total scheduled service revenues per ASM for the first quarter 2017 decreased roughly 4.4 percent over last year, driven by capacity growth from a mix of peak and off-peak (both seasonal and day-of-the-week) flying, as well as Easter shifting into the second quarter, including service into our newest cities - Nashville, Tennessee; Sarasota/Bradenton, Florida; and Charleston, South Carolina.

Planning and development for Sunseeker Resorts is ongoing. Construction is expected to begin in June 2018, with the opening of ~~2017. In~~ the ~~current competitive environment, we expect industry capacity trends will continue to put pressure on yield.~~resort planned for early 2020.

RESULTS OF OPERATIONS

Comparison of three months ended March 31, ~~2017~~2018 to three months ended March 31, ~~2016~~2017

Operating Revenue

~~Scheduled service~~Passenger revenue. ~~Scheduled~~Passenger revenue now includes both scheduled service revenue ~~for~~and air-related ancillary revenue, due to the implementation of the New Revenue Standard. For the first quarter ~~2017~~2018, passenger revenue increased ~~by 5.2~~14.1 percent compared to ~~2016.~~2017. The increase was ~~primarily~~ driven by a ~~10.8~~15.2 percent increase in scheduled service passengers offset by a ~~5.1~~1.0 percent decrease in scheduled service average ~~base fare which was affected by the shift of Easter into the second quarter as well as a 10 percent increase in off-peak capacity quarter over quarter.~~

~~Ancillary air-related charges~~. ~~Ancillary air-related charges for the first quarter 2017 increased 8.8 percent compared to 2016, due mostly to the increase in scheduled service passengers.~~fare. The increase was diluted by a 1.8 percent decrease in average ancillary air-related fare per passenger which correlates with a 3.4 percent reduction in stage length, as shorter-haul trips tend to produce lower ancillary charges.

~~Ancillary third party products~~. The following table details the calculation of ancillary revenue from third party products. Third party products consist of revenue from the sale of hotel rooms, ground transportation (rental cars and hotel shuttle products), attraction and show tickets, and fees we receive from other merchants selling products through our website:

~~(1) Includes payment expenses and travel agency commissions.~~

~~Ancillary third party revenue increased 13.2 percent for the first quarter 2017 compared to 2016 as a result of our~~ increase in scheduled service passengers ~~as well as~~is due to a 9.5 percent increase in departures and a 2.9 percentage point increase in load factor.

Third party products revenue. Third party product revenue ~~generated from~~for the first quarter 2018 decreased 19.0 percent overall compared to 2017, due mostly to the allocation of certain revenue components of our Allegiant World Mastercard® co-branded credit card, ~~program which launched in third~~

Fixed fee contract revenue. Fixed fee contract revenue for the first quarter ~~2017 increased $4.5 million~~2018 decreased 6.2 percent from ~~2016~~2017. This was planned and expected due ~~mostly~~ to ~~increased~~less availability of aircraft for charter flying ~~for both the Department of Defense and under~~during our ~~Apple Vacations charter.~~fleet transition.

Operating Expenses

We primarily evaluate our expense management by comparing our costs per passenger and per ASM across different periods, which enables us to assess trends in each expense category. The following table presents operating expense per passenger for the indicated periods. The table also presents operating expense per passenger, excluding fuel, a statistic which gives management and investors the ability to measure and monitor our cost performance absent fuel price volatility. Both the cost and availability of fuel are subject to many economic and political factors beyond our control.

Aircraft fuel expense. Aircraft fuel expense increased ~~57.8~~25.2 percent for the first quarter ~~2017~~2018 compared to ~~2016~~2017 as the system average fuel cost per gallon increased by ~~40.3~~20.4 percent, ~~and~~coupled with a 3.8 percent increase in system fuel gallons consumed ~~increased 12.8 percent (resulting from~~on a ~~12.5~~10.4 percent increase in system ~~capacity).~~ASMs. ASM growth outpaced fuel consumption as fuel efficiency (measured as ASMs per gallon) increased 6.4 percent year over year, due to increased flying on our Airbus aircraft which are more fuel efficient.

Salary and benefits expense. Salary and benefits expense increased ~~39.1~~$16.7 million or 17.3 percent for the first quarter ~~2017~~2018 when compared to the same period last year. The increase is largely attributable to ~~$14.2 million in incremental expense related to the collective bargaining agreement with our pilots, which went into effect in August 2016, as well as costs associated with~~ a ~~16.7~~6.8 percent increase in the number of full-time equivalent employees needed to support additional operating aircraft and the transition to a

single fleet type. Additionally, ~~stock compensation expense~~the collective bargaining agreement with our flight attendants went into effect January 1, 2018. In conjunction with this agreement, flight attendant salaries increased ~~incrementally~~an average of 14 percent year over year. There were also annual salary increases for our pilots, as dictated by ~~$2.5 million related to management equity grants which were not in place in first quarter 2016.~~their collective bargaining agreement.

Station operations expense. ~~Stations~~Station operations expense ~~increased 3.6 percent~~ for the first quarter ~~2017~~2018 increased 18.1 percent on a 9.5 percent increase in scheduled service departures compared to the same period in ~~2016.~~2017. The increase in expense outpaced the increase in departures due to expired incentives and an increase in various supplementary station expenses.

Maintenance and repairs expense. Maintenance and repairs expense for the first quarter ~~2017 increased 13.6~~2018 decreased $10.8 million, or 36.0 percent compared to the same period in ~~2016. This~~2017. The year-over-year decrease is largely due ~~partially~~ to ~~a 3.0 percent~~ ~~increase in the average number~~nine fewer heavy maintenance events performed on our MD-80 series aircraft, which are being systematically retired from our operating fleet. The cost of aircraft in service, as well as the mix of maintenance activities resulting in more expensive parts repairs and routine maintenance in first quarter 2017. We expect routine maintenance expenses for our used Airbus aircraft to increase over time as repair costs for these aircraft are generally more expensive than similarmajor maintenance events for our ~~MD-80 aircraft.~~Airbus aircraft is deferred in accordance with the deferral method of accounting and the amortization of these expenses is included under depreciation and amortization expense.

Depreciation and amortization expense. Depreciation and amortization expense for the first quarter ~~2017 increased 23.8~~2018 decreased $2.4 million, or 7.9 percent, ~~compared~~year over year. The decrease is largely due to ~~2016, on a 3.0 percent increase in~~ the ~~average number of aircraft in service. Depreciation expense for the remainder of 2017 will continue to outpace 2016 as~~ retirement of our MD-80 ~~aircraft has been accelerated to 2019 or earlier and, as~~aircraft. As a result of the ~~related~~

impairment charge taken on our MD-80 fleet in fourth quarter 2017, we no longer have aircraft depreciation expense ~~will increase in 2017, 2018 and 2019~~associated with this fleet type. Depreciation expense related to ~~account~~the MD-80 aircraft for the ~~acceleration. The increase~~three months ended March 31, 2017 was ~~also impacted~~$6.4 million.

This decrease in depreciation and amortization expense was partially offset by higher incremental monthly depreciation expense associated with our Airbus aircraft, as we continue to add Airbus aircraft into service. Depreciation expense related to the ~~amortization~~ownership of the Airbus A320 series aircraft was $18.2 million for the first quarter 2018 compared to $12.8 million for the same period in 2017. Amortization of major maintenance ~~for our Airbus aircraft in accordance with~~costs under the deferral method of ~~accounting. Prior~~accounting for the Airbus aircraft was $2.5 million for the first quarter 2018 compared to $1.3 million for the ~~second~~first quarter ~~2016, we had not incurred any major maintenance costs on our Airbus aircraft.~~2017.

Sales and marketing expense. Sales and marketing expense for the first quarter ~~2017~~2018 increased ~~$4.2~~$5.7 million compared to the same period in ~~2016,~~2017, mostly due to an increase in net credit card fees paid by us. We previously charged for credit card fee reimbursement (a fee charged to customers for using a credit card) at zero margin, which was applied as a reduction to sales and marketing expense, and the net amount paid by us for credit card fees was reduced. We discontinued the charge for credit card fee reimbursement in January 2017, although this charge was still applicable for travel booked up to the discontinuation date. With the discontinuation of the credit card surcharge, credit card fee reimbursements for the first quarter (whichpaid. There were ~~recorded as reductions of sales and marketing expense) declined to $3.4 million from $7.0 million in first quarter 2016, accounting for the majority of the increase in this line item year over year.~~

~~Other operating expense.~~ ~~Other operating expense for the first quarter 2017~~also year-over-year increased ~~$2.7 million compared to 2016. The increase in expense is primarily due to losses recorded on disposed aircraft parts in 2017 compared to a gain of over $2.0 million recorded on an engine sale in 2016~~expenses related to ~~one of~~various marketing initiatives for our ~~retired Boeing 757-200 aircraft.~~growing network.

Income Tax Expense

Our effective tax rate ~~remained relatively flat quarter over quarter, at~~was 20.5 percent for the three months ended March 31, 2018, compared to 37.0 percent for the three months ended March 31, ~~2017, compared to 37.3 percent~~2017. The effective tax rate for the three months ended March 31, ~~2016. The effective tax rate for 2017~~2018 differed from the statutory federal income tax rate of ~~35.0~~21.0 percent primarily due to the dissolution of foreign subsidiaries, offset by state and foreign taxes, the adoption of ASU 2016-09 related to share-based payments, as well as executive compensation deduction limitations. The effective tax rate for the same period in 2016 differed from the federal tax rate due to executive compensation deduction limitations as well as state and foreign taxes.

While we expect our tax rate to be fairly consistent in the near term, it will vary depending on recurring items such as the amount of income we earn in each state and the state tax rate applicable to such income. Discrete items during interim periods may also affect our tax rates.

Cash, restricted cash and investment securities (short-term and long-term) ~~increased~~decreased from ~~$470.5~~$501.9 million at December 31, ~~2016~~2017 to ~~$537.6~~$490.1 million at March 31, ~~2017.~~2018. Restricted cash represents escrowed funds under fixed fee contracts and cash collateral against letters of credit required by hotel properties for guaranteed room availability, airports and certain other parties. Under our fixed fee flying contracts, we require our customers to prepay for flights to be provided by us. The prepayments are escrowed until the flight is completed and are recorded as restricted cash with a corresponding amount as air traffic liability. Investment securities represent highly liquid marketable securities which are available-for-sale.

During the first three months of ~~2017,~~2018, our primary source of funds was ~~$147.0~~$172.9 million generated by ~~operations as well as $22.0 million in proceeds from long-term debt issuance.~~operations. Our operating cash flows and previous borrowings have allowed us to invest in our fleet transition and return ~~value~~capital to shareholders. Our future capital needs are primarily for the acquisition of additional aircraft, including our existing Airbus A320 series aircraft commitments, as well as potential capital outlay related to Sunseeker Resorts as well as other travel and leisure initiatives. Of the 26 aircraft expected to be placed into service during the remainder of 2018, 13 are structured as capital leases and will not require separate financing, and 10 have already been paid for (representing the aircraft already returned or being returned from lease to a European carrier).

We believe we have more than adequate liquidity resources through our operating cash flows, borrowings, and cash balances, to meet our future contractual ~~obligations, and expect to finance a significant portion of the purchase price of our newly manufactured Airbus aircraft order on acceptable terms. We~~obligations. In addition, we continue to consider raising funds through debt financing on an opportunistic basis.

In addition to our recurring quarterly cash dividend, we plan to continue repurchasing our stock in the open market subject to availability of cash resources and compliance with our debt covenants. ~~As of March 31, 2017, our~~Our current repurchase authority ~~under our board-approved stock repurchase program was $86.8~~is $100 million. There is no expiration ~~date for the~~to this program.

Debt

Our long-term debt obligations, without reduction for related issuance costs, decreased from ~~$813.2~~$1,171.0 million as of December 31, ~~2016~~2017 to ~~$808.6~~$1,068.1 million as of March 31, ~~2017.~~2018 as we paid off our senior secured revolving credit facility and continued making scheduled repayments on our existing debt. During the first quarter of 2018, we did not enter into any new debt agreements.

Sources and Uses of Cash

Operating Activities. During the three months ended March 31, ~~2017,~~2018, our operating activities provided ~~$147.0~~$172.9 million of cash compared to ~~$160.4~~$146.6 million during the same period of ~~2016.~~2017. The year-over-year ~~decrease~~increase in ~~reported~~ cash inflows ~~was primarily impacted by~~is the ~~$30.3~~result of a $12.8 million ~~decrease~~increase in net ~~income.~~income as well as changes in various asset and liability accounts, including a $24.8 million year-over-year increase in accrued liabilities.

Operating cash inflows are primarily derived from providing air transportation and related ancillary products and services to customers, and we expect to use that cash flow to purchase aircraft and equipment, make scheduled debt payments, and return capital to shareholders through share repurchases and dividends.

Investing Activities. Cash used in investing activities was ~~$125.4~~$65.4 million ~~for~~during the three months ended March 31, ~~2017~~2018 compared to ~~$66.1~~$125.4 million for the same period in ~~2016.~~2017. The year-over-year ~~increase~~decrease is mostly due ~~mostly~~ to ~~our net~~investment security activity, as cash proceeds from investment securities (net of purchases) were $3.3 million in the first three months of 2018 compared to cash used to purchase investment securities (net of ~~proceeds from maturities)~~proceeds) of $67.2 million for the same period in ~~2017, compared~~2017.

Financing Activities.

The year-over-year increase is primarily due to ~~a decrease~~an increase in ~~dividends~~principal payments on long-term debt and capital lease obligations, as we paid $102.9 million in debt and ~~share repurchases~~capital lease payments in the ~~current quarter. In~~ first quarter ~~2017,~~2018 compared to $26.4 million for the same period in 2017. Our debt payments in the first quarter 2018 included various balloon payments, as well as the payoff of our senior secured revolving credit facility, which had $41.6 million in outstanding principal as of December 31, 2017. Additionally, we did not receive any funds from issuance of new debt during the first quarter 2018, whereas we received $22.0 million in loan proceeds during the same period in 2017. For the three

months ended March 31, 2018, we repurchased $2.2 million of common stock ~~for $4.9 million~~ and paid cash dividends of ~~$11.7~~$11.3 million, compared to the repurchase of $4.9 million in common stock ~~for $55.6 million~~ and payment of cash dividends of ~~$32.8~~$11.7 million ($27.7 million of which was a special dividend declared in December 2015) in the same period of 2016. We also paid $4.4 million in debt payments net of proceeds in first quarter 2017, compared to $9.3 million of proceeds from the issuance of debt net of principal payments duringfor the same period in ~~2016.~~2017.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

~~A description~~In the first quarter of 2018, there were no changes to our critical accounting policies ~~is included~~and estimates from those disclosed in ~~Item 7 of~~the Consolidated Financial Statements and accompanying notes contained in our ~~Annual Report on~~2017 Form 10-K, except as discussed below relating to the New Revenue Standard.

Effective January 1, 2018, we adopted the New Revenue Standard using the full retrospective method, which resulted in the recast of the 2017 prior period data presented. Under this ASU and subsequently issued amendments, revenue is recognized at the time a good or service is transferred to a customer for the ~~year ended December 31, 2016. There has been no material change to these policies during the three months ended March 31, 2017.~~amount of consideration received.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are subject to certain market risks, including commodity prices (specifically aircraft fuel). The adverse effects of changes in these markets could pose potential losses as discussed below. The sensitivity analysis provided does not consider the effects that such adverse changes may have on overall economic activity, nor does it consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ.

Aircraft Fuel

Our results of operations can be significantly impacted by changes in the price and availability of aircraft fuel, as aircraft fuel expense represented ~~27.9~~30.7 percent of our operating expenses for the three months ended March 31, ~~2017.~~2018. Increases in fuel prices, or a shortage of supply, could have a material impact on our operations and operating results. Based on our fuel consumption for the three months ended March 31, ~~2017,~~2018, a hypothetical ten percent increase in the average price per gallon of fuel would have increased fuel expense by approximately ~~$8.6~~$10.7 million. We have not hedged fuel price risk ~~in recent~~for many years.

Interest Rates

We have market risk associated with changing interest rates due to the short-term nature of our cash and investment securities and variable-rate debt. We invest available cash in government and corporate debt securities, investment grade commercial

paper, and other highly rated financial instruments. Because of the short-term nature of these investments, the returns earned closely parallel short-term floating interest rates. A hypothetical 100 basis point change in interest rates for the three months ended March 31, 2018 would have impacted interest income from cash and investment securities by approximately $1.2 million.

As of March 31, ~~2017,~~2018, we had ~~$468.1~~a total of $601.4 million in variable-rate debt, including current maturities and without reduction for related costs. A hypothetical 100 basis point change in market interest rates for the three months ended March 31, 2018, would have affected interest expense by approximately $1.6 million.

As of March 31, 2018, we had $466.7 million of fixed-rate debt, including current maturities and ~~excluding~~without reduction for related costs, which had a fair value of ~~$482.9~~$474.0 million. A hypothetical 100 basis point change in market interest rates would not impact interest expense or have a material effect on the fair value of our fixed-rate debt instruments as of such date.

See Item 7A "Quantitative and Qualitative Disclosures About Market Risk" in the Company's Annual Report on Form 10-K for the year ended December 31, ~~2016,~~2017, for further information about market risk.

Item 4. Controls and Procedures

As of March 31, ~~2017,~~2018, under the supervision and with the participation of our management, including our chief executive officer (“CEO”) and chief financial officer (“CFO”), we evaluated the design and operation of our disclosure controls and procedures of the Securities Exchange Act of 1934, as amended, or the “Exchange Act.” Based on this evaluation, our management has concluded that our disclosure controls and procedures are designed, and are effective, to give reasonable assurance that the information we are required to disclose is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon this evaluation, management concluded that our disclosure controls and procedures are effective in providing reasonable assurance that information required to be disclosed in our reports filed with the SEC under the Exchange Act is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure.

There were no changes in our internal control over financial reporting that occurred during the quarter ending March 31, ~~2017,~~2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Effective January 1, 2018, we adopted Accounting Standards Codification 606, “Revenue from Contracts with Customers”. Although the new revenue standard is not expected to have a material impact on our ongoing net income, changes were made to relevant business processes and the related control activities, including information systems, in order to monitor and maintain appropriate controls over financial reporting. The operating effectiveness of these changes will be evaluated as part of our annual assessment of the effectiveness of internal controls over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

We are subject to certain legal and administrative actions we consider routine to our business activities. We believe the ultimate outcome of any pending legal or administrative matters will not have a material adverse impact on our financial position, liquidity or results of operations.

Item 1A. Risk Factors

We have evaluated our risk factors and determined there are no changes to the risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K.
