WestJet cancelled more than 300 flights on August 5, 2026, as it continues to recover from a one-day flight attendant strike that took place on August 3. The cancellations represent a significant portion of WestJet’s scheduled flights across Canada, with further disruptions expected as the airline works to restore its network.
Operational Recovery Challenges
WestJet entered a recovery phase after ending the strike through a tentative agreement with CUPE 8125, representing 4,400 flight attendants. Ahead of the strike, the airline stored an unknown number of Boeing 737s and repositioned aircraft and crews domestically and overseas. A WestJet spokesperson noted on August 4 that
“flights have begun to operate; however, the impacts of the disruption continue as the airline works to restore its network.” Data from Cirium showed 16 cancellations on August 4 by 11 a.m. Eastern time, following over 300 cancellations on strike day.
Passenger Impact and Overseas Stranding
More than 300,000 travellers were affected by cancellations and delays tied to the strike and its aftermath, including Canadians stranded overseas. Marsha Manuel, a passenger delayed in Lisbon, Portugal, described her experience of being without timely rebooking, hotel accommodation, or meal vouchers after her flight home was cancelled by WestJet on August 4. Similar difficulties were reported for passengers
traveling to and from cities such as Copenhagen, Denmark and various airports in New Brunswick, including Miramichi, Greater Moncton Romeo LeBlanc International Airport, Fredericton International Airport, and Halifax International Airport.
Official Statements on Strike Resolution
The Canadian Union of Public Employees local CUPE 8125 confirmed flight attendants reached a tentative agreement with WestJet that ended the strike, with workers returning to their positions. WestJet announced it was resuming operations and encouraged passengers to check flight statuses before departure. The airline extended its flexible cancellation policy through August 6, 2026, allowing one-time booking changes or cancellations without fees. WestJet has committed to refunding or reaccommodating guests
affected by strike-related cancellations or delays.
Passenger Rights and Expert Advice
Under Canadian Air Passenger Protection Regulations administered by the Canadian Transportation Agency, WestJet must provide alternative travel arrangements within 48 hours for cancelled or delayed flights caused by the strike, including reimbursement or compensation for delays exceeding three hours. This may include rebooking on competitor airlines or through alternate airports when necessary. Aviation expert John Gradek of McGill University advised passengers not to cancel and rebook flights independently, as doing so can forfeit their regulatory protections. Instead, travellers should await WestJet’s rebooking notices and retain all receipts related to incurred expenses.
Recovery Timeline and Route Disruptions
Gradek estimated that
it will take until Friday or Saturday, August 7 or 8, 2026, for WestJet’s flight schedule to approach normalcy, with a full backlog of delayed passengers potentially requiring one to two weeks to clear. The strike occurred during the peak summer travel season, complicating recovery since many remaining flights are already at full capacity. The disruptions impacted WestJet routes within Canada, including between Calgary and Edmonton, and international routes to Europe, notably Lisbon, Portugal, and Copenhagen, Denmark.
