N745NK

The airframe bearing registration N745NK is an Airbus-built narrow-body delivered in 2025 with manufacturer serial number 12333. This specific hull is an example of the Airbus A321-271NX sub-variant and is owned and operated by Spirit Airlines, a corporation based in the United States. The aircraft is registered on the US registry and was placed into service with its current operator upon build in 2025, a notable single-step ownership timeline with no intervening operators recorded. At the time of manufacture the airframe had an estimated market valuation of $60,000,000, indicative of a late-production, entry-into-service condition.

The aircraft operates in a high-density Spirit Airlines configuration featuring 235 seats, arranged as 8 Big Front Seats + 227 economy (Spirit high-density layout). Typical missions for this airframe focus on short- to medium-haul point-to-point routes consistent with its 4,000 nm range and operator network; cruise speed is listed at 450 kts with a maximum certified ceiling of 39,800 ft. Specific avionics fit and line maintenance records are not published in the supplied data, though continued operation on a single operator fleet simplifies component commonality and scheduled maintenance flows. As a high-density configured A321-271NX, turnaround and cabin servicing are central operational considerations for Spirit’s route model.

The Airbus A321-271NX sits within the A320neo family targeting airlines requiring single-aisle, high-capacity, fuel-efficient operations. With PW1100G-JM powerplants in the PW1133G thrust rating and a 4,000 nm range, it competes against high-capacity variants of the Boeing 737 MAX family for similar missions. Demand for such configured aircraft is driven by low-cost carriers seeking seat-mile cost efficiencies, while maintenance and resale considerations hinge on engine life, seating density conversion potential, and the airframe’s late-build status—factors reflected in the $60,000,000 valuation.
