Bombardier Aerospace (BBA, Montréal Trudeau) President (Commercial Aircraft), Fred Cromer, has confirmed the Canadian manufacturer is looking to revise its Delta Air Lines A220-100 delivery schedule given concerns the US International Trade Commission (ITC) could approve, in early 2018, a recent US Department of Commerce decision to slap a 300% duty on the aircraft.

"We are looking at alternative opportunities for aircraft to be delivered to other customers," Cromer told Reuters at the Dubai Airshow.

While Cromer declined to specify with whom Bombardier was talking, he did confirm Bombardier intended to meet previous deliver commitments of up to forty-five C-Series jets in 2018 even if the Delta order is held up. Delta is due to take delivery of its first A220-100 during the first half of 2018.

Should the ITC chose to tax the Canadian-manufactured C-Series, a possible solution could lie in the firm's recent decision to sell the C-Series aircraft programme to Airbus (AIB, Toulouse Blagnac) which has an already active production plant in Alabama. Bombardier has said any Alabama-made C-Series jets destined for the US market could be exempted from any punitive duties.
