Formerly known as the Bombardier CSeries, the Airbus A220 is quickly establishing itself as a favorite among both airlines and their passengers when it comes to lower-demand short-haul routes. The twin-engine narrowbody family currently consists of the A220-100 and A220-300 variants, with data from Airbus showing that 67 A220-100s and 312 A220-300s have been delivered to customers thus far.
