N101DU

This entry describes airframe N101DU, an Airbus A220-100 (formerly Bombardier CS100) built in 2018 with manufacturer's serial number 50020. The airframe is owned and operated by Delta Air Lines, Inc., a corporate operator based in Atlanta, GA, US, and is registered in the US. The airframe was produced by Airbus and is notable within Delta's fleet as part of the airline's introduction of the A220 family; delivery and entry into Delta service reflect the platform's transition after Bombardier's CSeries program became the Airbus A220. No separate valuation or damage history is published for this specific registration.

Airframe N101DU operates in Delta's 109-seat configuration marketed for its regional and thin-medium density mainline routes, with a cabin split of 12 First / 15 Delta Comfort+ / 82 Main Cabin. The flightdeck is equipped with a Rockwell Collins Pro Line Fusion (5-panel glass cockpit) suite, supporting modern navigation, situational awareness and commonality with other Pro Line-equipped fleet types. Typical mission profiles for this airframe include short- to medium-haul domestic and transborder services from Delta’s Atlanta base, leveraging the A220-100’s range and cruise performance. Maintenance considerations follow corporate heavy-visit schedules and Pratt & Whitney PW1524G engine support programs typical for operator fleets; no unique airframe-specific modifications are published.

The Airbus A220-100 occupies a performance niche between regional jets and larger single-aisle airliners, offering competitive fuel burn, cabin comfort and range for 100–130 seat missions. As delivered to Delta, N101DU represents a response to airline demand for right-sized mainline aircraft competing against variants of Embraer E2 family and smaller A320neos in certain markets. Resale and maintenance considerations for this airframe align with established support from Airbus and Pratt & Whitney for the A220 family, and the commonality of the Pro Line Fusion cockpit supports crew training and operational integration.
