Air Canada and a union representing the airline’s flight attendants have come to a tentative agreement, ending a days-long strike that canceled thousands of flights and stranded passengers.

The strike, which ended on Tuesday, focused attention on why many airlines don’t start paying flight attendants until the plane doors are shut.

TORONTO (AP) — Air Canada said Tuesday it will gradually restart operations after reaching an agreement with the union for 10,000 flight attendants to end a strike that disrupted the travel plans of hundreds of thousands of travelers.
