Alaska Air Group, Inc. today reported first quarter 2010 net income of $5.3 million, or $0.15 per diluted share, compared to a net loss of $19.2 million, or $0.53 per diluted share, in the first quarter of 2009. Excluding mark-to-market fuel hedge losses of $12.5 million ($7.8 million after tax or $0.21 per diluted share), the company reported first quarter 2010 net income of $13.1 million, or $0.36 per diluted share, compared to a net loss excluding special items of $25.4 million, or $0.70 per diluted share, in the first quarter of 2009.

"Producing a profit in our seasonally weakest period is particularly noteworthy," said Bill Ayer, Alaska Air Group’s chairman and chief executive officer. "The last time we reported a significant first-quarter profit was in 1999.

"Our results were driven by higher load factors, improving pricing trends and good cost management. Selective schedule reductions coupled with entry into new markets also contributed to our strong performance and provide a foundation for continued improvement.

"Our operational results continue to be outstanding. For the most recent 12-month DOT reporting period, Alaska held the No. 1 spot in on-time performance among the 10 largest U.S. airlines. And recently, Horizon was ranked among the world’s top five airlines for 2009 on-time performance. I want to thank all our employees for running a safe, reliable operation and providing outstanding customer service."

The following table reconciles the company’s adjusted net income and earnings per diluted share (EPS) during the first quarters of 2010 and 2009 to amounts as reported in accordance with GAAP (in millions except per-share amounts):

  Note A:  Pursuant to Regulation G, we are providing disclosure of the
  reconciliation of reported non-GAAP financial measures to their most
  directly comparable financial measures reported on a GAAP basis. We 
  believe that consideration of this measure of unit costs excluding 
  fuel, purchased capacity costs, and other noted items may be important
  to investors for the following reasons:

  -- By eliminating fuel expense and certain special items from our unit
  cost metrics, we believe that we have better visibility into the results
  of 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 excluding fuel and certain special items is one of the 
  most important measures used by managements of both Alaska and Horizon 
  and by the Air Group Board of Directors in assessing quarterly and 
  annual cost performance.

  -- Cost per ASM excluding fuel (and other items as specified in our plan
  documents) is an important metric for the employee incentive plan that
  covers company management and the majority of other employee groups.

  -- Cost per ASM 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 new pilot contract transition costs and fleet 
  transition costs, 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 "mainline" passenger unit revenues for 
  Alaska, we do not (nor are we able to) evaluate mainline unit revenues
  excluding the impact that changes in fuel costs have had on ticket 
  prices.  Fuel expense represents a large percentage of our total mainline
  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.

  Line of Business Information:
  -----------------------------
  Horizon brand flying includes those routes in the Horizon system not
  covered by the Alaska Capacity Purchase Agreement (CPA).  Horizon
  bears the revenue risk in those markets and, as a result, traffic,
  yield and load factor impact revenue recorded by Horizon.  In the
  CPA arrangement, Horizon is insulated from market revenue factors
  and is guaranteed contractual revenue amounts based on operational
  capacity.  As a result, yield and load factor information is not
  presented.

  Glossary of Financial Terms

ASM – Available seat miles or "capacity." Represents total seats available across the fleet multiplied by the number of miles flown.

RPM – Revenue passenger miles or "traffic." The number of those available seats that were filled with paying passengers. One passenger traveling one mile is one RPM.

RASM – Total operating revenue divided by ASMs. Operating revenue includes all passenger revenue, freight and mail, Mileage Plan and other ancillary revenue — commonly called "unit revenue" and represents the average total revenue for flying one seat one mile.

PRASM – Passenger revenue per ASM — commonly called "passenger unit revenue."

Yield – Passenger revenue per RPM. This represents the average revenue for flying one passenger one mile.

CASM – Total operating costs per ASM. This represents all operating expenses, including fuel and special items — commonly called "unit cost."

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 costs are largely out the company’s control.

Economic fuel – Best estimate of the cash cost of fuel, net of the impact of the company’s fuel-hedging program.

Mainline – Represents flying on Alaska jets and all associated revenue and costs.

Purchased capacity flying – Represents operations whereby Horizon and, to a much lesser extent, another small carrier in the state of Alaska fly certain routes for Alaska using Horizon’s or the other carrier’s fleets.
