N125DU

This airframe, registered as N125DU, is an Airbus A220-100 (BD-500-1A10) built in 2019 with manufacturer serial number 50044. It is owned and operated by Delta Air Lines, Inc., a corporation based in the United States, and carries a United States registration. The aircraft is valued at $80,000,000 and, since delivery, has been operated in Delta's regional and mainline short- to medium-haul network. It is recorded as entered into service in 2019 under Delta ownership and has remained on the U.S. registry.

The cabin for this specific airframe follows Delta's configuration as Delta 109-seat: 12 First / 15 Comfort+ / 82 Main, reflecting a mixed premium and high-density single-aisle layout for short- and medium-haul routes. Avionics fit and specific line maintenance history for this serial are not published, though the A220 family typically carries modern integrated flight decks; maintenance for the PW1500G geared turbofan requires operator familiarity with geared-fan inspections and vendor-supported shop visits. Typical mission profiles for N125DU include intra-continental sectors and higher-frequency city pairs within Delta's U.S. network, operated from Delta’s hubs and mainline operating bases. Unique amenities are per Delta’s cabin specification rather than aircraft-specific modifications on record.

The Airbus A220-100 (BD-500-1A10) family positions itself in the 100–130 seat market segment as a fuel-efficient, long-range single-aisle alternative to older regional jets and smaller narrowbodies. With a 3,600 nm range and cruise near 447 kts, the type competes against stretched regional jets and smaller narrowbodies for longer thin routes and frequency-driven schedules. Demand among mainline carriers for this model is driven by its passenger comfort, fuel efficiency, and lower operating costs relative to legacy designs. Resale and maintenance considerations for this airframe reflect the contemporary nature of the type, the PW1500G engine support environment, and its continuity of single-owner operation under Delta Air Lines, Inc.
