WestJet flight attendants, represented by the Canadian Union of Public Employees (CUPE), issued a strike notice, triggering a 72-hour lockout notice from the airline starting early morning August 13, 2026. Mass cancellations of hundreds of WestJet flights began on August 14, 2026, affecting travelers across Canada.
WestJet’s Daily Flights and Passenger Impact
WestJet operates over 600 flights daily and employs 4,400 flight attendants. Aviation experts estimate that the strike and subsequent cancellations could disrupt travel plans for up to 75,000 passengers within the initial 72-hour period. WestJet allows customers to cancel or reschedule flights without fees during a flexible booking window covering July 30 to August
4, 2026. Flights operated by WestJet Encore on Q400 aircraft and WestJet codeshare flights by partner airlines are not affected by the strike. Travelers can access updated travel advisories and compensation information on WestJet’s official website.
Labor Dispute Causes and Union Demands
The dispute centers on pay and working conditions, specifically flight attendants’ request to be compensated for their entire shift—from check-in to clock-out—including ground delays that are currently unpaid. CUPE, representing both WestJet and Air Canada flight attendants, argues that younger crew members face financial difficulties working in expensive cities like Toronto. The union’s push for increased pay follows a similar strike by Air Canada
flight attendants in August 2025, which caused major flight disruptions across Canada.
Official Statements from WestJet and CUPE
WestJet CEO Alexis von Hoensbroech stated, “The decision to issue a lockout notice, in response to the actions taken by the union, was not one that was made lightly. We sincerely regret the inconvenience and uncertainty this continues to cause for our guests.” He emphasized the airline’s commitment to minimizing guest and crew disruption: “We greatly value the work and contributions of our Cabin Crew, and it is our responsibility to ensure the integrity of our network and to minimize the risk of stranding our guests, crew and
aircraft.”
CUPE president Alia Hussain affirmed, “We’ve been clear from the start that we want to reach a fair deal without a strike.” WestJet also announced enhanced flexibility for passengers during peak summer travel, allowing changes or cancellations without fees for flights booked between July 30 and August 4, 2026.
Passenger Impact and Communication
Travelers should expect cancellations and delays primarily affecting WestJet flights within Canada, including routes to and from Toronto and Calgary. Those booked directly through WestJet will receive email notifications about changes. Passengers who booked via travel agencies or online platforms must contact their respective agents for updates and rebooking. Affected
passengers will be refunded or accommodated as necessary. WestJet is actively negotiating with CUPE but has prepared its network for further disruption if an agreement is not reached within the 72-hour deadline.
Industry Context and Past Labor Actions
WestJet holds approximately 30% of Canada’s domestic air travel market. The current strike threat follows the August 2025 strike by Air Canada flight attendants, which grounded about 700 flights daily and affected roughly 500,000 passengers. During that strike, United Airlines assisted stranded passengers, and the Canadian government intervened without preventing the eventual walkout. Both WestJet and Air Canada flight attendants’ unions are represented by CUPE, highlighting ongoing regional
labor tensions in Canada’s aviation sector.
