A tentative agreement has been reached to end the contract dispute between Air Canada and its flight attendants, both the airline and the Canadian Union of Public Employees announced Tuesday.

The airline said operations will gradually restart after a deal was reached with the union, ending a strike that caused hundreds of flight cancellations and hit 500,000 customers.

Air Canada's flight attendant union reached a tentative agreement with the country's largest airline, after a multi-day strike that temporarily halted operations.
