What was the Airbus A220 called before Airbus adopted its current name?

The Airbus A220 was called the Bombardier CSeries before Airbus adopted its current name.

The CSeries was a clean-sheet family of narrow-body passenger aircraft developed by Bombardier Aerospace in Canada. It was designed for the lower end of the single-aisle market, with the CS100 seating fewer passengers than the CS300. The aircraft made its first flight in 2013 and entered commercial service with Swiss International Air Lines in 2016.

Airbus acquired a majority stake in the CSeries programme in 2018. As part of that agreement, Bombardier’s CS100 became the Airbus A220-100, while the CS300 became the Airbus A220-300. The rebranding gave Airbus a modern small-aircraft family while expanding the programme’s international sales and production network.

The A220 name therefore refers to the same basic aircraft lineage, not a completely new design created after the Airbus partnership. Its Pratt & Whitney geared turbofan engines and high use of composite materials remain important features of the family.
