The flight took place a few days after the aircraft rolled out of the paint shop. Next, the aircraft will continue with pre-delivery testing and assembly, as elements of its interior come together at the A220 assembly line. Delta's first A220 is scheduled to begin service in early 2019.
Delta Air Lines will be the first U.S. airline to operate the A220 – at the same time becoming the fourth A220 operator, after Swiss International Air Lines, airBaltic, and Korean Air. Delta is the largest A220-100 customer, with a firm order for 75 aircraft.
The A220-100 delivers unbeatable fuel efficiency. It brings together state-of-the-art aerodynamics, advanced materials and Pratt & Whitney's latest-generation PW1500G geared turbofan engines to offer at least 20 percent lower fuel burn per seat compared to previous generation aircraft.
With an order book of over 400 aircraft to date, the A220 has all the credentials to win the lion's share of the 100- to 150-seat aircraft market, estimated to represent at least 7,000 aircraft over the next 20 years.
