A crippling strike by Air Canada flight attendants that grounded thousands of flights over wages and unpaid labor is the latest blow to the airline industry's compensation system that does not fully pay cabin crews for their hours at work.

Air Canada flights will resume Tuesday evening, it said. Details were sparse on the tentative deal between the company and its flight attendants union, CUPE.

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.
