N57409

This airframe, registered as N57409, is a Boeing 737-9 MAX built in 2025 with manufacturer serial number 68818. The aircraft is owned and operated by United Airlines, a corporation based in Chicago, IL, USA, and is registered in the US. Delivered into United mainline service upon completion in 2025, the airframe entered operation with the operator’s two-class configuration and an operator-specific avionics fit; its book value is listed at $130,000,000, reflecting new-build pricing and entry-condition status for the type. No additional historic ownership transfers or registry remarks are published beyond the original manufacturer-to-operator delivery.

The cabin on N57409 is configured as United mainline two-class seating with 20 business seats and 159 economy seats (C20 Y159), providing a 179-seat single-aisle layout tailored for medium- to long-haul domestic and transcontinental missions. The cockpit features an updated 737 MAX flight deck with large-format displays; specific avionics fit and operator-customized systems vary by airline, and this airframe carries United’s operator-specific installation. Typical mission profiles for this airframe include high-density domestic trunk routes and transcontinental services that exploit the model’s extended range; maintenance considerations follow the 737 MAX program schedules and operator heavy-check cycles under United’s mainline maintenance program.

The Boeing 737-9 MAX is positioned in the single-aisle, higher-capacity end of the MAX family, competing with larger narrowbodies for dense short- to medium-haul markets and some longer thin transcontinental sectors. With 2× CFM LEAP-1B powerplants and a 3,550 nm range, the type targets airlines seeking higher seat count efficiencies and improved fuel burn versus previous-generation 737s; resale and maintenance considerations center on LEAP engine support, MAX-specific structural and software program maintenance, and strong operator demand for mainline replacements.
