Investor Update – December 19, 2008

References in this update to “Air Group,” “Company,” “we,” “us,” and “our” refer to Alaska Air Group, Inc. and its subsidiaries, unless otherwise specified.

This update includes forecasted operational and financial information for our subsidiaries Alaska Airlines, Inc. (Alaska) and Horizon Air Industries, Inc. (Horizon). Our disclosure of operating cost per available seat mile, excluding fuel and other items, provides us (and may provide investors) with the ability to measure and monitor our performance without these items. The most directly comparable GAAP measure is total operating expense per available seat mile. However, due to the large fluctuations in fuel prices, we are unable to predict total operating expense for any future period with any degree of certainty. In addition, we believe the disclosure of fuel expense on an economic basis is useful to investors in evaluating our ongoing operational performance. Please see the cautionary statement under “Forward-Looking Information.”

We are providing unaudited information about fuel price movements and the impact of our hedging program on our financial results. Management believes it is useful to compare results between periods on an “economic basis.”Economic fuel expense is defined as the raw or “into-plane” fuel cost less the cash we receive from hedge counterparties for hedges that settle during the period, offset by the premium expense that we recognize. Economic fuel expense more closely approximates the net cash outflow associated with purchasing fuel for our operation.

Forward-Looking Information

This update contains forward-looking statements subject to the safe harbor protection provided by Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995.

*For Alaska, our forecasts of mainline cost per ASM excluding fuel, restructuring charges and fleet transition costs is based on forward-looking estimates, which will likely differ from actual results.

**Because of the volatility of fuel prices, actual amounts may differ significantly from our estimates. Our forecasted economic fuel expense includes the net cost of hedges settled during the period. We expect the amount to be approximately $5.5 million during the fourth quarter for Alaska.

Restructuring Charges Expected in Fourth Quarter

As previously announced, we expect charges in the fourth quarter related to Alaska’s reduction in work force that began during the third quarter. The original estimate of this fourth quarter charge was $15 million to $20 million. Based on information currently available, the estimate has been revised to $8 million to $10 million. The final amount of the charge could differ from this estimate.

2009 Capacity Guidance

As previously announced, we currently expect capacity in the first quarter of 2009 to be down between 10% and 12% and down approximately 8% for full year 2009 compared to the same periods in 2008. These capacity plans are subject to change.

ALASKA – PURCHASED CAPACITY

Alaska has Capacity Purchase Agreements (CPA) with Horizon for certain routes and with a third party for service between Anchorage and Dutch Harbor, AK.

November 2008 Statistics

The following data represents on the Horizon CPA flying as that flying represents approximately 95% of the total purchased capacity.

Line-of-Business Information

Horizon’s line-of-business traffic and revenue information is presented below. In CPA arrangements, Horizon is (or was, in the case of the Frontier CPA which ended in November 2007) 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. Horizon bears the revenue risk in its brand flying markets. Revenue from the Alaska CPA is eliminated in consolidation.

*For Horizon, our forecast of cost per ASM excluding fuel and fleet transition costs is based on forward-looking estimates, which will likely differ significantly from actual results.

Fleet Transition Charges Expected in Fourth Quarter

We currently expect fleet transition charges of between $2 million and $3 million associated with the transition out of two CRJ-700 aircraft that were removed from operations during the fourth quarter and delivered to a third party under a sublease arrangement. We expect further charges in 2009 as we exit the remaining fleet, although we cannot estimate the amount or timing of any 2009 charges at this time.

2009 Capacity Guidance

As announced previously, we currently expect capacity in the first quarter of 2009 to be 14% to 15% lower than the first quarter of 2008. Additionally, our expectation is that full year 2009 capacity will decline by approximately 9%, although plans for the full year have not yet been finalized.

*All of our 2008, 2010 and 2011 positions and the majority of our 2009 positions are call options which are designed to effectively cap our cost of the crude oil component of our jet fuel purchases. With call options, we benefit from a decline in crude oil prices, as there is no downward exposure other than the premiums we pay to enter into the contracts.

As previously disclosed, we are modifying our hedge portfolio to take advantage of the recent and rapid decline in oil prices. We have terminated certain hedges that were originally scheduled to settle in 2009 and 2010 and replaced those instruments with new hedges that have lower strike prices. Upon termination of these hedges, the cash that we receive has been significantly less than the original premium we paid for the hedge contract. The net economic cost of the modifications that we have made thus far in the fourth quarter is approximately $35 million (measured as the difference between the original premium paid and the proceeds received upon termination). This amount will not be included in our calculation ofeconomic fuel expenseand will therefore be excluded from our presentation of “adjusted” results for the period. We believe that restructuring our hedge portfolio provides important strategic benefit because it significantly reduces our exposure to increases in fuel costs in 2009 and beyond.

Impact of Boeing Strike and Deferral of Q400 Deliveries

Due to the machinist strike at Boeing, Alaska will experience delays in the delivery of 737-800 aircraft. We have received an updated delivery schedule from Boeing, which is reflected in the projected fleet count table below. Horizon has negotiated a deferral of Q400 deliveries with Bombardier to retime those deliveries to coincide with the successful remarketing and transition out of the CRJ-700 aircraft. The tables below reflect the revised schedule.

Capital Expenditures

Total expected capital expenditures for 2008 and 2009 are as follows (in millions):



	Total 2008 Estimate			Total 2009 Estimate
	Aircraft-related	Non-aircraft	Total	Aircraft-related	Non-aircraft	Total
Alaska	$225*	$45	$270*	$350*	$60	$410*
Horizon	75	5	80	70	5	75
Air Group	$300	$50	$350	$420	$65	$485

* The amount above is presented net of the expected return of $80 million of pre-delivery payments from Boeing to reflect the timing of B737-800 aircraft deliveries that were deferred as a result of the Boeing strike. This return reduces the expected capital expenditures in 2008 and increases the expected amount for 2009.

Alaska (B737-800)	1	10	6	4	21
Horizon (Q400)	—	5	7	1	13
Totals	1	15	13	5	34

In addition to the firm orders noted above, Alaska has options to acquire 45 additional B737-800s and Horizon has options to acquire 10 Q400s. Alaska has notified Boeing of its intent to exercise the option on one 737-800 for delivery in 2009. Once that option has been converted to a firm commitment, we will have seven firm commitments for B737-800 aircraft in 2010.

* The expected fleet count at December 31, 2009 for Alaska is subject to change. We plan to sell up to four B737-700 aircraft in 2009 as a result of our capacity reductions, which is reflected in the 2009 changes above.

** F=Freighter; C=Combination freighter/passenger

*** All remaining Q200 aircraft have been taken out of scheduled service, but are expected to operate as spare aircraft through the end of January 2009.

**** The planned CRJ and Q400 fleets at December 31, 2009 are subject to change as we finalize the fleet transition plan and is dependent on our ability to remarket the CRJ aircraft.
