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.

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.

Thousands of flight attendants must still approve the agreement. The walkout, which began Saturday, has disrupted half a million travelers’ plans, the airline said.
