Delta ordered 75 A220s in 2016 and last month ordered 15 more and upgraded to a larger version, the A220-300, for the new orders and a portion of its previous orders.
The larger A220-300s with 120 seats will be assembled at an Airbus facility in Mobile, Ala., and will begin entering Delta’s fleet in 2020.
Delta has not yet announced when the A220 will begin flying routes from Atlanta, but CEO Ed Bastian has said the plane will “touch the entire domestic system over time.”
“Atlanta will see it at the right time,” he said.
The A220 started out as the Bombardier C Series CS100. Then, a tariff dispute broke out with Boeing. The Trump administration proposed tariffs of more than 200 percent, but the U.S. International Trade Commission ended up overturning the tariffs on Montreal-based Bombardier.
In the middle of the dispute, Airbus acquired a majority interest in the C Series business and announced plans to eventually open a final assembly facility for the plane in Mobile.
