N721NK

This airframe, registered as N721NK, is an Airbus A321-271NX (A321neo) built in 2024 with manufacturer's serial number 12009. The aircraft is owned and operated by Spirit Airlines, a United States–based carrier, and is registered in the US. Entered into service with Spirit in 2024 and recorded at a market valuation of $64,000,000, the airframe reflects a late-production A321neo example in normal operational condition.

The production cabin for this airframe is recorded as C8 / Y227, though the operator layout may vary and Spirit Airlines commonly configures high-density single-aisle layouts of approximately 228 seats; this specific aircraft is listed with 235 seats. The flight deck is the Airbus A320-family integrated glass cockpit with full fly-by-wire controls, suitable for single-crew operations under the airframe’s certified systems. Typical mission profiles for this aircraft include short- to medium-haul domestic and transcontinental sectors within Spirit’s network, exploiting the neo’s improved fuel efficiency and extended range. Maintenance considerations follow Airbus A321neo schedules and PW1100G-type engine shop visit planning, with operator maintenance baselines set by Spirit’s heavy maintenance providers.

The Airbus A321-271NX is positioned in the single-aisle, high-capacity narrowbody niche, offering extended range and improved fuel burn relative to previous A321ceo models. Competing airframes in its mission set include stretched variants of the Boeing 737 MAX and other high-density narrowbodies used by ultra-low-cost carriers. Demand among low-cost and leisure carriers remains strong for late-production neo examples like this one, aiding liquidity on the secondary market; resale and long-term maintenance considerations hinge on airframe utilization, engine shop visit cycles for the PW1133G, and the evolving configuration needs of high-density operators.
