Air Canada flight attendants have reached a tentative agreement with the airline, ending a nearly four-day strike that grounded flights and stranded over 500,000 passengers.

More than 10,000 crew members walked out over pay and scheduling, rejecting government back-to-work orders before mediated talks led to a breakthrough on Tuesday.

The proposed deal includes immediate pay raises of 8–12% and new ground pay for pre-flight duties, which CUPE hailed as a “historic” win, the BBC has reported.

Flights have begun resuming, though Air Canada says full service will take days to restore. The agreement still requires ratification by union members.
