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

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

Air Canada and the union representing 10,000 flight attendants resumed talks late Monday for the first time since the strike began over the weekend. The strike is affecting about 130,000 travelers a day at the peak of the summer travel season.
