Air Canada and the union representing Canadian flight attendants have reached a tentative deal to end the strike that started Saturday. It will resume flights.

The union representing thousands of striking Air Canada flight attendants says it will risk jail time and fines but will not order its members back to work, despite the federal labour relations board calling the strike illegal.

Air Canada said it will gradually begin restarting its operations after strike action grounded its flights since August 16. It said the first flights are scheduled for Tuesday evening, but that it could take seven to ten days to restore its full service, and that some flights will be cancelled during that period.
