WestJet has cancelled 81 flights scheduled for August 1, 2026 as part of a planned network reduction ahead of a potential flight attendant strike set to begin no earlier than August 2. The airline confirmed the cancellations by 10:30 p.m. MT on July 31, citing the need to protect its operational integrity.
Labour Negotiations and Strike Notices
The Canadian Union of Public Employees (CUPE), representing approximately 4,400 WestJet flight attendants, issued a 72-hour strike notice that expires shortly after midnight on August 2, 2026. WestJet responded with a lockout notice on the same 72-hour timeline. As of July 31, no tentative agreement has been reached
between the union and WestJet, prolonging labour negotiations.
Reason for Flight Cancellations
WestJet described the flight cancellations as essential to maintaining network integrity and minimizing the risk of guests and aircraft being stranded. The airline emphasized that this organized reduction allows full operational control and timely communication with passengers and crew during the labour uncertainty.
Flight Cancellation Details and Affected Routes
According to analytics from Cirium, the routes with the highest number of cancellations include Calgary (YYC) to Vancouver (YVR) with four flights cancelled, Vancouver to Calgary with three, and two cancellations each on routes between Cancún (CUN) and Toronto Pearson (YYZ), Edmonton (YEG) and Calgary, Victoria (YYJ) and Calgary,
as well as Toronto to Vancouver and back.
Passenger Impact and Travel Advice
WestJet has advised travellers to verify the status of their flights, offering one-time flight changes or cancellations with no fees for travel between July 30 and August 4, 2026. WestJet Encore flights operated with Q400 aircraft and codeshare flights by partners are not affected by the strike or cancellations. Passengers will only receive disruption notifications if their flights are cancelled. Updates are available through WestJet’s Travel Advisory page.
Sunwing Vacations, part of the WestJet Group, reported that most of its flights remain on schedule despite the cancellations.
Official Statements
WestJet said in an official
statement: “To ensure the integrity of WestJet’s network, and to minimize the risk of stranding guests and aircraft, the airline has started to issue cancellations and reduce flying.” It also added, “These actions ensure the airline has complete control of its operations and can communicate with guests and crew to minimize people being stranded.” The airline reaffirmed its commitment to negotiating a tentative agreement recognizing the professionalism of its cabin crew.
CUPE president Alia Hussain expressed hope to avoid a strike, stating, “We have made some progress, and the issues remaining need to be resolved at the table. We are
hopeful that we can still avoid a strike and remain committed to resolving this there.” At Toronto Pearson Airport, passenger Alyesha Singh commented, “We just hope everything comes a conclusion before we get back.”
Context of August Long Weekend Travel
The cancellations and potential strike come during the August long weekend, a period of high travel demand in Canada. WestJet is preparing to park Boeing 737 aircraft in case the strike commences. While the disruption is centered on WestJet’s mainline operations, Sunwing Vacations flights remain largely unaffected.
