N637FR

The airframe bearing tail number N637FR is an Airbus-built narrowbody completed in 2024 with manufacturer serial 11860 and type designation Airbus A321-271NX. The aircraft is owned and operated by Frontier Airlines, an airline based in the United States, and is registered under the US registry; it was delivered into Frontier's fleet in 2024 and entered U.S. registration upon entry into service. No public valuation or detailed condition report has been published for this specific airframe. Serial 11860 identifies this unit within Airbus production records and links it to the A321neo family production ramp-up in the mid-2020s.

This airframe is configured in a high-density, single-class layout identified as High-density single-class (Y240) — 240 seats, reflecting Frontier Airlines' ultra-economy seating philosophy and maximized revenue-seat planning. Typical mission profiles for the type and this configuration include medium- to long-range domestic and transcontinental sectors up to its quoted 4,000 nm ferry range, with cruise operations commonly conducted near 472 kts and cruise ceilings to 39,000 ft. Avionics and systems fit align with the A321-271NX standard equipment package offered by Airbus, while maintenance cycles and operational utilization follow Frontier's fleet policies; specific supplemental amenities or bespoke cabin modifications for N637FR have not been published.

The Airbus A321-271NX is a member of the A321neo family that targets high-capacity short- to medium-haul routes with improved fuel efficiency and passenger capacity relative to previous A320 family derivatives. Equipped with Pratt & Whitney PW1100G-JM geared turbofans, the type competes with high-density variants of the Boeing 737 MAX and other single-aisle, stretched narrowbodies for airlines seeking lower seat-mile costs. Buyer demand for high-density A321neo variants remains strong for carriers focused on domestic growth, while resale and maintenance considerations center on engine shop visits, structural checks associated with high-utilization layouts, and the marketability of a 240-seat single-class cabin in secondary markets.
