Exhibit 99.1

Investor Update - December 14, 2023

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 expected operational and financial information, including operating cost per available seat mile, excluding fuel and other items (CASMex). Our disclosure of CASMex, 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 expenses per available seat mile. Please see the cautionary statement under “Forward-Looking Information.”

We are providing information about estimated fuel prices. 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 any cash we receive from hedge counterparties for hedges that settle during the period, offset by the recognition of premiums originally paid for those hedges that settle during the period. 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.

All of the forward-looking statements are qualified in their entirety by reference to the risk factors discussed therein. We operate in a continually changing business environment, and new risk factors emerge from time to time. Management cannot predict such new risk factors, nor can it assess the impact, if any, of such new risk factors on our business or events described in any forward-looking statements. We expressly disclaim any obligation to publicly update or revise any forward-looking statements after the date of this report to conform them to actual results.

FINANCIAL UPDATE

The table below reflects our updated expectations for Q4 2023:

	Q4 Expectation	Previous Q4 Expectation
Capacity (ASMs) % change versus 2022	13% to 14%	11% to 14%
Total revenue % change versus 2022	2.25% to 3.25%	1% to 4%
CASMex % change versus 2022	Down ~5%	Down 3% to 5%
Economic fuel cost per gallon	~$3.40	$3.30 to $3.40
Adjusted pre-tax margin %	~1%	0% to 2%

Our CASMex guide has improved to the better end of our prior guide, driven by our strong operational performance and cost execution. Revenue is also coming in slightly ahead of our original midpoint, driven by strong holiday bookings and improved close in demand. Fuel costs, in particular West Coast refining margins, have remained volatile throughout the quarter due to further unplanned maintenance events at California refineries, resulting in a revised economic fuel cost per gallon toward the high end of our previously guided range. As a result, we have narrowed our adjusted pre-tax margin guidance to the midpoint of our previous range.

In December, we are increasing our share repurchase activity. We now expect to repurchase $145 million in shares in 2023, which will more than offset dilution for the full year. We are also revising our full year 2023 capex guidance from $1.7 billion to $1.6 billion, as certain aircraft payments have shifted into next year. For 2024, we expect to further reduce capital expenditures to approximately $1.4 billion to $1.5 billion for the full year.
