Alaska Airlines expands use of Boeing 737 MAX fleet on key winter routes

According to scheduling data from Cirium, Alaska Airlines plans to operate over 8,000 flights using its Boeing 737 MAX family in December 2025. These flights will provide more than 1.4 million seats and nearly 2.6 billion available seat miles during that month.

The Boeing 737 MAX 9 will account for over 7,000 of these flights. Internationally, its most frequent route will be between Los Angeles (LAX) and Liberia in Costa Rica, with Cancun also receiving regular service from LAX using this model. Domestically, the Seattle-Tacoma International Airport serves as a central hub for the airline’s MAX operations; Anchorage is scheduled for up to seven daily flights from Seattle on some days in December. Other major destinations served multiple times daily include San Diego, Kona, New York JFK, Newark, Maui, and Phoenix.

For the smaller Boeing 737 MAX 8 jets, Alaska Airlines plans around a thousand flights during December. About a quarter of these will be international routes—most notably daily service from LAX to Guatemala City and near-daily service to San Jose in Costa Rica. On domestic routes, the busiest corridor is between Los Angeles and Seattle-Tacoma with only about two dozen scheduled flights throughout the month. Other notable domestic connections include Seattle-San Jose and Portland-San Diego.

With continued expansion of its modern narrowbody fleet and strategic deployment across key markets this winter season, Alaska Airlines aims to meet passenger demand efficiently across both short- and long-haul networks.
