N921AK

This airframe, registered as N921AK, is a Boeing airliner of the model Boeing 737-9 MAX, manufacturer Boeing, built in 2021 with manufacturer serial number 43337. The aircraft is owned by ALASKA AIRLINES INC (a corporation based in Seattle, WA, US) and is registered in the US. Valued at approximately $53,000,000, the airframe entered service in 2021 and has been operated from its owner’s primary base; the ownership record indicates corporate operation by Alaska Airlines since introduction into the fleet.

The cabin configuration for this specific airframe is arranged for 178 total seats with 16 Business, 24 Economy Comfort, and 138 Economy seats, reflecting a mixed-class short- to medium-haul layout optimized for high-density single-aisle operations. Operated by ALASKA AIRLINES INC, the aircraft’s typical mission profile includes domestic and near-international routes that leverage the model’s 3,550 nm range and 453 kt cruise speed for efficient airline scheduling. Avionics and systems are consistent with the Boeing 737-9 MAX line-fit standards and LEAP-1B powerplant integration, with maintenance considerations focused on operator-standard heavy checks and engine support for the LEAP family. Cabin amenities follow the operator’s fleet practices for premium and economy zones; any unique retrofit items or supplemental modifications are not published for this airframe.

The Boeing 737-9 MAX family occupies the high-capacity single-aisle niche, competing against stretched variants of the Airbus A320neo family in mainline short- and medium-haul markets. With twin CFM International LEAP-1B engines delivering roughly 29,320 lbf each, the type balances fuel efficiency and range for dense route networks. Buyer demand for this model is driven by airlines seeking commonality with existing 737 fleets and favorable seat-mile economics; resale and maintenance considerations center on engine support agreements and airframe market values such as the $53,000,000 estimate for this specific aircraft.
