Alaska Air Group (ALK) delivered a mixed bag of fourth-quarter results on Thursday, combining solid profitability with revenues that didn't quite hit the mark. The airline reported sales growth of 3% year over year to $3.63 billion, just shy of the $3.64 billion analysts were expecting. But here's where it gets interesting: the company managed to post adjusted earnings of 43 cents per share against guidance of only 10 cents and consensus estimates of 12 cents. That's the kind of beat that makes investors sit up and pay attention.

Demand Holds Steady Despite Headwinds

Fourth-quarter revenue per available seat mile (RASM) edged up 0.6% year over year, which Alaska management attributed to resilient demand despite a temporary slowdown triggered by the November government shutdown. Corporate travel showed particular strength, climbing 9% year over year, with close-in bookings and yields bouncing back from earlier pressures.

The airline's diversified revenue streams delivered across the board. Premium cabin revenue jumped 7%, cargo operations grew 22%, and the loyalty program contributed 12% more revenue compared to the prior year. These aren't trivial numbers when you're trying to build margin in an industry notorious for razor-thin profitability.

Alaska also continued returning cash to shareholders, buying back 0.7 million shares for roughly $30 million during the quarter. That brings total 2025 repurchases to $570 million. The company closed December with $627 million in cash and equivalents on the balance sheet.

Cost Control and Operational Updates

The Seattle-based carrier expanded capacity (available seat miles) by 2.2% year over year while keeping unit costs excluding fuel, freighter operations, and special items to just 1.3% growth. Management highlighted this as evidence their cost control initiatives are working. Economic fuel costs came in at $2.57 per gallon for the quarter, reflecting higher refining prices on the West Coast.

On the expansion front, Alaska opened bookings for new Seattle-London and Seattle-Rome routes launching in spring 2026. The airline also broadened its international reach by enabling transactions in six currencies and launching Japanese, Korean, and Italian-language websites to capture more overseas bookings.

A Cautiously Optimistic View Ahead

Here's where the narrative gets complicated. Alaska says early January 2026 bookings are running ahead of last year, with several record days already in the books. First-quarter managed corporate revenues are tracking 20% higher year over year, which sounds fantastic. The company expects strong unit revenues with roughly flat earnings per share, representing sequential improvement from recent quarters.

But then comes the guidance. Alaska projects capacity growth of 2% to 3% for fiscal 2026 and 1% to 2% for the first quarter. More notably, the airline expects adjusted earnings of $3.50 to $6.50 per share for the full year, well below the consensus estimate of $5.26. For the first quarter alone, management anticipates an adjusted loss of $0.50 to $1.50 per share versus street expectations of a 50-cent loss.

The company maintains it's still on track to deliver $10 in earnings per share and $1 billion in incremental profit by 2027, but that wide 2026 range suggests management sees considerable uncertainty ahead.

Massive Boeing Order Signals Long-Term Ambitions

In January 2026, Alaska placed its largest fleet order ever, committing to 105 Boeing (BA) 737-10 jets and five Boeing 787 aircraft, with options for 35 additional 737-10s. The deal will expand the fleet to approximately 475 aircraft by 2030 and more than 550 by 2035, underscoring the airline's confidence in long-term growth despite near-term caution.

Alaska Air shares traded down 1.04% to $48.35 in premarket action Friday following the results.
