Alaska Air Group Reports Second Quarter 2017 Results

Financial Highlights:

• Reported net income for the second quarter under Generally Accepted Accounting Principles ("GAAP") of $296 million or $2.38 per diluted share, compared to net income of $260 million, or $2.10 per diluted share in 2016. As the acquisition of Virgin America Inc. ("Virgin America") closed on Dec. 14, 2016, second quarter 2017 information reflects the results of Virgin America, including the impacts associated with purchase accounting. Second quarter 2016 results do not include Virgin America.

• Reported second quarter net income, excluding merger-related costs and mark-to-market fuel hedging adjustments, of $312 million, compared to $263 million in the second quarter of 2016. Adjusted diluted earnings per share were $2.51, compared to $2.12 in the second quarter of 2016. This quarter's results were in line with First Call analyst consensus estimate of $2.52 per share.

• Paid $0.30 per-share quarterly cash dividend in the second quarter, a 9% increase over the dividend paid in the second quarter of 2016.

• Generated approximately $1.1 billion of operating cash flow and used approximately $512 million for capital expenditures, resulting in $572 million of free cash flow in the second quarter of 2017.

• Held $1.9 billion in unrestricted cash and marketable securities as of June 30, 2017.

Operational Highlights:

• Launched nine new routes during the quarter and announced 10 new routes, including obtaining final approval from the Department of Transportation for three routes to Mexico City.

• Took delivery of two of five Airbus A321neos scheduled for delivery in 2017, becoming the first airline to operate this aircraft.

• Began jet service at Horizon with the first flights of the new Embraer 175 jets after taking delivery of the first six of 33 aircraft scheduled for delivery over the next two years.

• Entered into an agreement with the International Brotherhood of Teamsters to amend the eight-year contract with Horizon's pilots, providing Horizon the ability to attract and retain the best pilots in the regional industry.

• Added Finnair as a global Mileage Plan partner.

Recognition and Awards:

• Ranked "Highest in Customer Satisfaction Among Traditional Carriers" in 2017 by J.D. Power for the 10^th year in a row.

Note A: Pursuant to Regulation G, we are providing reconciliations of reported non-GAAP financial measures to their most directly comparable financial measures reported on a GAAP basis. We believe that consideration of these non-GAAP financial measures may be important to investors for the following reasons:

• By eliminating fuel expense and certain special items (including merger-related costs) from our unit metrics, we believe that we have better visibility into the results of operations and our non-fuel cost-reduction initiatives. Our industry is highly competitive and is characterized by high fixed costs, so even a small reduction in non-fuel operating costs can result in a significant improvement in operating results. In addition, we believe that all domestic carriers are similarly impacted by changes in jet fuel costs over the long run, so it is important for management (and thus investors) to understand the impact of (and trends in) company-specific cost drivers such as labor rates and productivity, airport costs, maintenance costs, etc., which are more controllable by management.

• Cost per ASM (CASM) excluding fuel and certain special items, such as merger-related costs, is one of the most important measures used by management and by the Air Group Board of Directors in assessing quarterly and annual cost performance.

• Adjusted income before income tax and CASM excluding fuel (and other items as specified in our plan documents) are important metrics for the employee incentive plan, which covers the majority of Air Group employees.

• CASM excluding fuel and certain special items is a measure commonly used by industry analysts, and we believe it is the basis by which they compare our airlines to others in the industry. The measure is also the subject of frequent questions from investors.

• Disclosure of the individual impact of certain noted items provides investors the ability to measure and monitor performance both with and without these special items. We believe that disclosing the impact of certain items, such as merger-related costs and mark-to-market hedging adjustments, is important because it provides information on significant items that are not necessarily indicative of future performance. Industry analysts and investors consistently measure our performance without these items for better comparability between periods and among other airlines.

• Although we disclose our passenger unit revenues, we do not (nor are we able to) evaluate unit revenues excluding the impact that changes in fuel costs have had on ticket prices. Fuel expense represents a large percentage of our total operating expenses. Fluctuations in fuel prices often drive changes in unit revenues in the mid-to-long term. Although we believe it is useful to evaluate non-fuel unit costs for the reasons noted above, we would caution readers of these financial statements not to place undue reliance on unit costs excluding fuel as a measure or predictor of future profitability because of the significant impact of fuel costs on our business.

GLOSSARY OF TERMS

Aircraft Utilization - block hours per day; this represents the average number of hours per day our aircraft are in transit

Aircraft Stage Length - represents the average miles flown per aircraft departure

ASMs - available seat miles, or “capacity”; represents total seats available across the fleet multiplied by the number of miles flown

CASM - operating costs per ASM, or "unit cost"; represents all operating expenses including fuel and special items

CASMex - operating costs excluding fuel and special items per ASM; this metric is used to help track progress toward reduction of non-fuel operating costs since fuel is largely out of our control

Debt-to-capitalization ratio - represents adjusted debt (long-term debt plus the present value of future operating lease payments) divided by total equity plus adjusted debt

Diluted Earnings per Share - represents earnings per share ("EPS") using fully diluted shares outstanding

Diluted Shares - represents the total number of shares that would be outstanding if all possible sources of conversion, such as stock options, were exercised

Economic Fuel - best estimate of the cash cost of fuel, net of the impact of our fuel-hedging program

Free Cash Flow - total operating cash flow generated less cash paid for capital expenditures

Load Factor - RPMs as a percentage of ASMs; represents the number of available seats that were filled with paying passengers

Mainline - represents flying Boeing 737 and Airbus 320 family jets and all associated revenues and costs

PRASM - passenger revenue per ASM; commonly called “passenger unit revenue”

Productivity - number of revenue passengers per full-time equivalent employee

RASM - operating revenue per ASMs, or "unit revenue"; operating revenue includes all passenger revenue, freight & mail, Mileage Plan and other ancillary revenue; represents the average total revenue for flying one seat one mile

Regional - represents capacity purchased by Alaska from Horizon, SkyWest and PenAir. In this segment, Regional records actual on-board passenger revenue, less costs such as fuel, distribution costs, and payments made to Horizon, SkyWest and PenAir under the respective capacity purchased arrangement (CPAs). Additionally, Regional includes an allocation of corporate overhead such as IT, finance, other administrative costs incurred by Alaska and on behalf of Horizon.

RPMs - revenue passenger miles, or "traffic"; represents the number of seats that were filled with paying passengers; one passenger traveling one mile is one RPM

Yield - passenger revenue per RPM; represents the average revenue for flying one passenger one mile
