Canadian airline to start cancelling flights ahead of planned strikeLightRocket via Getty ImagesAir Transat, one of Canada's largest airlines, said it will start gradually suspending some flights starting on Monday ahead of a planned strike. The union representing the airline's pilots issued a 72-hour strike notice on Sunday, announcing that Air Transat pilots will stop showing up to work on Wednesday if a contract agreement is not reached. Following the strike notice, the airline said it would gradually shut down its operations "to prevent the consequences of a sudden, unplanned interruption". The airline called the strike notice "premature" while a union leader said there is still time to avoid the strike."No pilot wants to strike, but Air Transat management has left us no choice," Capt Bradley Small, who heads a group of pilots within the union, said in a statement.
