N77588

This airframe, registered as N77588, is a Boeing 737-9 MAX built in 2024 with manufacturer's serial number 43446. The aircraft is owned by United Airlines, Inc. (a corporation based in Chicago, IL, US) and carries a United States registration. Delivered new to the named corporate owner in 2024, the airframe represents an in-service example of the current-production single-aisle MAX family and is maintained to the operator's standard fleet condition protocols.

The subject aircraft is outfitted in a two-class 179-seat configuration consistent with the operator's typical layout: 20 First / 48 Economy Comfort / 111 Economy. With the installed CFM International LEAP-1B powerplants and a published range of 3,300 nm at a cruise speed of 470 kts, this airframe is configured to perform medium- to longer-range single-aisle missions within the operational envelope up to its certified ceiling of 41,000 ft. As part of the owning corporation’s fleet, the aircraft follows the operator’s standard maintenance and cabin-refurbishment practices for in-service narrowbody units.

The airframe is a member of the Boeing 737-9 MAX family produced by Boeing Commercial Airplanes, representing a fixed-wing multi-engine category asset with contemporary high-bypass turbofan installations (LEAP-1B). With a 179-seat two-class interior and a 3,300 nm range capability, this variant occupies a performance niche offering higher capacity on single-aisle routes while relying on modern engine technology for fuel efficiency. Market considerations for units of this type center on demand from large network carriers seeking dense single-aisle capacity and fleet commonality, with maintenance and resale influenced by engine configuration and interior seating density.
