Airbus A220-100
The original CSeries — Bombardier's clean-sheet 100-seater, now flying under the Airbus name · First flight 2013 · In service 2016
The A220-100 began life as the Bombardier CS100, the smaller half of the all-new CSeries family that Bombardier launched at the Farnborough Airshow on 13 July 2008. The first aircraft flew from Mirabel on 16 September 2013, Transport Canada certified the type on 18 December 2015, and Swiss took the first delivery on 29 June 2016, flying its first revenue service on 15 July 2016.
Airbus took a 50.01 % majority stake in the programme on 1 July 2018 and renamed the CS100 the A220-100 ten days later; after Bombardier left the partnership in February 2020, Airbus held 75 % alongside Investissement Québec. Pratt & Whitney PW1500G geared turbofans, a composite wing and fly-by-wire controls give it airliner-class range in a 100–120-seat cabin, and it is certified for the steep approach into London City Airport.
Delta Air Lines became the first US operator in October 2018 and flew its first A220-100 service, LaGuardia to Dallas/Fort Worth, on 7 February 2019; it is by far the largest -100 operator. Swiss, ITA Airways and a handful of smaller airlines fly the rest — the smaller model is outsold heavily by the A220-300.
