In it, the U.S. plane maker alleges that the Canadian company sold the 75 C Series planes to Delta at "absurdly low prices" while benefiting from unfair subsidies from the Canadian, Quebec and British governments. Sept 27 (Reuters) - Delta Air Lines Inc's chief executive on Wednesday characterized as "bizarre" the claim by Boeing Co that rival planemaker Bombardier Inc is doing business unfairly and said he does not expect the U.S. government to impose stiff duties on the Canadian jets. “It’s not out of any anti-Canadian or any anti-U.K. or certainly any anti-Northern Ireland sentiment, but even with your friends and even with your allies, you must obey the rules,” Ross said, adding that the decision was preliminary and a final ruling is expected in months. In a preliminary decision issued Tuesday, the U.S. Department of Commerce ruled to put in place countervailing duties of nearly 220 per cent on C Series airliners, siding with Chicago-based Boeing Co. in its complaint against Montreal-based Bombardier Inc. Commerce will issue a final ruling on the matter in coming weeks, at which time the duties would go into effect. Canadian Prime Minister Justin Trudeau had put his government’s planned purchase of Boeing Super Hornet fighter jets on hold because of the trade dispute, saying it could not “do business with a company that’s busy trying to sue us and put our aerospace workers out of business.”

‘NOT A SLAM DUNK’

Boeing has argued that the military sale to the Canadian government and its petition against Bombardier are not linked.
The U.S. Commerce Department imposes preliminary anti-subsidy duties on Bombardier Inc. CSeries jets following American rival Boeing's claims of unfair Canadian subsidies. The penalty is on hold pending the U.S. International Trade Commission's final decision, expected in 2018.
