Alaska Airlines (AS, Seattle Tacoma International) is set to end A321-200N operations by the end of the current month with the type's last flight set to be AS1126 from Seattle Tacoma International to Los Angeles International, according to the ch-aviation schedules module.

Having inherited the Airbus jets from Virgin America via a now concluded merger, Alaska Airlines will once again be an all-Boeing operator in terms of mainline aircraft.

The ch-aviation fleets advanced module shows that the carrier has ten A321neo. While all of them were ordered by Virgin America before its merger with Alaska Air Group, only four were delivered to the low-cost carrier and the remaining six to Alaska Airlines. Five remain active, while the other five were retired in the first half of September 2023.

Alaska Airlines retired all ten A319-100s in 2020 and all fifty-three A320-200s by early 2023. The A321neo were to remain in service through the end of 2023, but the airline accelerated their phase-out.

The ch-aviation fleets advanced module reveals that Alaska Airlines' passenger B737 fleet comprises eleven B737-700s, fifty-nine B737-800s, fifty-six ACV!7M9s, twelve B737-900s, and seventy-nine B737-900ERs. It also has orders for ten B737-8s and thirty-one more -9s.
