WestJet cancelled 16 flights scheduled for August 4, 2026, as of 11 a.m. ET, continuing disruption after a flight attendants strike that began early Sunday. On August 3, the airline cancelled over 300 flights, representing about 62 percent of its schedule. The union involved in the labor dispute is CUPE Local 8125, representing 4,400 WestJet flight attendants across Canada.
Post-Strike Operations Underway
WestJet is in the process of ramping up operations following a tentative agreement reached with CUPE Local 8125 early on August 3. Contract talks began in Calgary in January 2026 and centred on wage increases and allegations of unpaid ground work
by cabin crew. While flights have resumed, the airline continues to reposition aircraft and crews to restore its network.
WestJet spokesperson Ashley Tymko said, “WestJet is resuming operations and entering the recovery phase following a labour disruption. Flights have begun to operate; however, the impacts of the disruption continue as the airline works to restore its network. Guests are encouraged to continue checking the status of their flights before heading to the airport.”
Passenger Impact and Protections
The strike forced WestJet to ground most flights across Canada early Sunday. To mitigate passenger impact, WestJet offered one-time fee-free changes or cancellations for passengers traveling between
July 30 and August 4, 2026. Customers affected by cancellations are eligible for refunds or re-accommodation. Under Canadian passenger protection regulations, WestJet must arrange transportation on competing carriers when necessary.
Union Ratification and Contract Background
Alia Hussain, president of CUPE Local 8125, said flight attendants have 30 days to ratify the tentative agreement, which includes pay increases. Further details have not been disclosed pending member briefings. The strike followed unsuccessful contract negotiations focused on wages and unpaid ground work.
