N668FR

This airframe, registered as N668FR, is an Airbus A321-271NX (A321neo) built in 2025 with manufacturer serial number 12486. The aircraft was produced by Airbus S.A.S. and is recorded as owned and operated by Frontier Airlines (a corporation based in the United States). Delivered new to Frontier in 2025, the airframe entered the carrier's high-density fleet program and has been registered in the US registry since delivery. Condition and valuation specifics have not been published publicly beyond its role in Frontier's single-class high-density configuration.

The aircraft is outfitted in a high-density single-class configuration, listed as Y240, accommodating 240 economy seats optimized for low-cost carrier operations. Typical mission profiles for this airframe emphasize medium- to long-haul single-aisle sectors within the continental United States and transcontinental services enabled by its 4,000 nm range and efficient neo-series engines. Avionics and systems conform to Airbus A321neo standard specifications as delivered by Airbus S.A.S., with operator-specific minor modifications for Frontier’s operational and crew-compatibility requirements. Maintenance for this specific airframe follows Frontier’s established A320/A321 fleet heavy- and line-maintenance cycles, with attention to the geared turbofan PW1133G-JM engines’ shop visit intervals and associated monitoring of performance parameters.

The Airbus A321-271NX (A321neo) occupies the single-aisle, high-capacity niche, offering improved fuel efficiency and range over previous A321ceo variants; the configuration of N668FR emphasizes maximum seat density for low-cost operations. Competing models in the same segment include stretched narrowbodies like the Boeing 737-10 and other A321neo subtypes; operators weighing acquisitions consider cabin density, engine type—here the IAE PW1133G-JM—and range capability (4,000 nm) against maintenance costs and residual value. For entrants and lessors, resale and lease prospects are influenced by the strong market demand for high-density A321neos among ULCCs and the fleet commonality benefits with existing A320-family operators.
