The Airbus A220-300, originally developed as the Bombardier CS300, is a clean-sheet narrowbody designed for the market between regional jets and the A320. Bombardier launched the aircraft in 2008 and first delivered it in 2016, but financial and trade pressures led Bombardier to sell majority control of the program to Airbus in 2018. Airbus rebranded the aircraft as the A220 and has been expanding the fleet in service. The A220-300 carries 130 to 150 passengers and offers a notably wider cabin than the 737 or A320, with larger windows, better air quality, and a quieter cabin thanks to the Pratt & Whitney geared turbofan engines. Delta Air Lines is the largest operator and has been using the aircraft on domestic routes where the A319 or 737-700 would previously have flown. Other major operators include JetBlue, Breeze Airways, Air France, Air Canada, and several leasing customers.
