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.

Air Canada flight attendants said Tuesday they had reached a "tentative" deal with the airline to end a strike over wages and ground work that has cancelled travel for half a million people worldwide.

Air Canada said it will gradually resume flights, but warned that a complete schedule could take up to a week.
