N450UP

This airframe, tail number N450UP, is a Boeing-built freighter completed in 1995 with manufacturer serial 25472. The airframe is a converted passenger-to-freighter configuration, registered in the US, and is owned by UNITED PARCEL SERVICE CO, a corporation based in Louisville, KY, US. As a main-deck palletized freighter operated by a major express integrator, this specific 757 has been maintained to airline cargo standards and employed in scheduled regional and transcontinental package feeder service under its corporate operator.

The aircraft carries a main-deck freighter (PF) configuration with palletized cargo on the main deck and forward flight-deck seating for flight crew, reflecting its conversion for dedicated cargo service. Typical missions for this airframe consist of express cargo and palletized freight runs that exploit the 757 airframe’s range and cruise speed to serve medium- to long-haul feeder and trunk routes for its corporate owner. Based with its owner in Louisville, KY, maintenance practices align with large-cargo operator programs, prioritizing rapid turnaround, structural checks associated with main-deck pallet operations, and engine shop visits suited to the RB211-535E4 powerplants.

The Boeing 757-24A(PF) occupies a performance niche as a narrow-body, medium-range freighter offering higher cruise speeds and transcontinental range compared with typical narrow-body freighters, which makes it attractive for integrators needing dense cargo capability without widebody infrastructure. Competing models for similar missions include other narrow-body conversions and smaller widebodies on longer transcontinental routes; buyer demand typically centers on operators seeking palletized main-deck volume, robust range, and favorable runway performance. Maintenance and resale considerations for this model emphasize RB211 engine support, freighter conversion structural life, and the strong secondary market among freight operators for well-maintained 757 freighters.
