Key Points
CUPE represents 4,400 flight attendants and issued 72-hour strike notice on July 30.
Strike could begin Sunday at 12:01 a.m. MT if no contract agreement reached.
Unpaid ground duties and credit hour compensation are the core negotiation dispute.
WestJet began parking 737 aircraft Friday and allows fee-free rebooking through August 4.
WestJet (WJA.TO) has begun parking its 737 aircraft ahead of a potential strike by 4,400 flight attendants that could begin Sunday at 12:01 a.m. MT. The Canadian Union of Public Employees issued a 72-hour strike notice on July 30, with the airline matching it with a lockout notice. Negotiations remain stalled over compensation for ground duties, threatening hundreds of daily flight cancellations during the August long weekend.
Strike deadline and what happens next
The 72-hour countdown expires Sunday just after midnight in Calgary, where WestJet is headquartered. If no deal is reached, either side can begin a work stoppage that would ground hundreds of flights during a busy travel weekend. CUPE, representing the flight attendants, said negotiations remain far apart on key issues. CEO Alexis von Hoensbroech stated the airline “greatly values” cabin crew but must “ensure the integrity of our network.”
Why ground pay is the core dispute
The central issue is unpaid work performed while flight attendants are still on the ground. CUPE says some boarding and pre-flight prep duties go unpaid. WestJet counters that these tasks are compensated through a “credit hour” system, where attendants earn $28.45 to $53.61 per credit hour. One credit hour equals roughly 1.5 duty hours, meaning 1,440 annual duty hours convert to 960 credit hours paid. The union rejects this model as insufficient.
How WestJet is preparing for disruption
WestJet began parking 737 aircraft on Friday to maintain operational control and prevent stranded passengers and crews. The airline is allowing passengers booked between July 30 and August 4 to change or cancel flights once without fees. Travellers with cancelled flights are eligible for refunds. WestJet Encore regional flights and code-share flights with partners like Delta Air Lines will not be affected by any strike.
Impact on Canadian travellers
The timing threatens the August long weekend, when many Canadians plan trips. WestJet operates about 75,000 passengers daily on just over 600 flights. Last summer, Air Canada flight attendants struck over similar unpaid ground work, with the stoppage lasting three days before a deal was reached. Some passengers booked through third-party sites like trip.com report difficulty rebooking directly with WestJet, which says third-party customers must contact their booking sites for assistance.
Final Thoughts
WestJet stock investors face operational uncertainty through the weekend. With the airline grounding aircraft and both sides still apart on pay, a strike appears increasingly likely unless talks accelerate. Investors should monitor Monday’s opening for any agreement announcement or service disruption confirmation.
