Today's Airbus A220-300 started life as the Bombardier CSeries CS300, launched in July 2008. It was Canada's bold bid to enter the mainline jet market, aimed at a size the big two had largely ignored. The smaller CS100 flew first in September 2013, and the stretched CS300 followed on February 27, 2015. airBaltic began service in December 2016. The design drew praise from reviewers right from the start.
Development costs nearly broke Bombardier. A 2017 trade fight with Boeing, which sought 300 percent US import duties, pushed the company to hand majority control to Airbus in 2018. The trade case collapsed, but the ownership change was permanent. Airbus brought scale, a global sales reach and cheaper parts, and the jets were rebranded A220-100 and A220-300. Bombardier was left with only a minority stake in its own jet.
A second assembly line then opened in Mobile, Alabama, and sales accelerated sharply. The -300 took the large majority of more than 900 A220 orders. airBaltic became the first all-A220 airline, while Delta, JetBlue, Air Canada, Breeze, Air France, Swiss, Korean Air and Qantas built fleets. It burns meaningfully less fuel per seat than re-engined rivals. Passengers and pilots rate it among the best small airliners flying.
