N636FR

This airframe, registered as N636FR, is an Airbus A321-271NX built in 2024 with manufacturer serial number 11839. The aircraft is owned and operated by Frontier Airlines, a corporation based in the United States, and carries a US registration. Registered in the United States upon completion in 2024 and retained by Frontier Airlines, the airframe represents a current-generation narrowbody addition to the carrier’s fleet and, as delivered new, would enter service in clean, manufacturer-fresh condition under the operator’s maintenance program.

The specific cabin configuration for N636FR follows Frontier Airlines’ operator standards for A321neo-family aircraft; typical layouts emphasize high-density single-class or mixed economy-plus arrangements suited to the carrier’s low-cost model. Onboard systems would include the manufacturer's standard avionics fit for the A321-271NX baseline, supporting modern flight deck capabilities and airline-specific modular cabin equipment. Mission profiles for this airframe are long-range narrowbody routes exploiting its 3,995 nm range and cruise near 450 kts, enabling transcontinental and select transborder missions from the operator’s U.S. bases. Routine maintenance considerations reflect Pratt & Whitney geared turbofan support for the PW1133G-JM engines and standard A321-series line and heavy maintenance cycles as defined by Airbus and Frontier’s engineering program.

The Airbus A321-271NX occupies a performance niche within the A320neo family as a longer-range, higher-capacity single-aisle option, offering roughly 3,995 nm range and high cruise speeds compared with earlier narrowbodies. Competing models include stretched variants from the same family and rival single-aisle types optimized for longer sectors; airlines value the type for fuel-efficient operations with the PW1133G-JM powerplants. For operators and lessors, considerations include engine support arrangements, aftermarket demand for late-production NEO-series frames, and resale or fleet redeployment potential given the aircraft’s 2024 build status and modern avionics and performance characteristics.
