WestJet passengers face a disrupted August long weekend after the airline cancelled 81 flights scheduled for Saturday, August 1. The cancellations are the first stage of a planned network reduction before a possible strike or lockout involving approximately 4,400 flight attendants.
WestJet confirmed the 81 cancellations as of 10:30 p.m. Mountain Time on July 31. The airline is parking aircraft gradually so planes, crews and passengers are not left in unsuitable locations if the labour dispute stops mainline operations.
What passengers need to know immediately
Travellers should not assume their flight is operating simply because they have not received a cancellation message. WestJet says it will contact affected customers directly, but passengers should check the official WestJet travel advisory and confirm every flight in their itinerary before going to the airport.
WestJet has not released a fixed public list of all cancelled flight numbers. Its schedule may change as aircraft are parked and negotiations develop, meaning additional cancellations could be announced with limited notice.
Sunday deadline does not guarantee a strike
CUPE Local 8125 issued a 72-hour strike notice on July 30, and WestJet responded with a lockout notice on the same timeline. Both notices expire shortly after midnight on Sunday, August 2, in Calgary.
Once the deadline passes, flight attendants could legally strike or the airline could lock them out. However, neither action is automatic. Negotiations remain underway, and both parties have said they hope to reach an agreement without a work stoppage.
Even a last-minute agreement may not immediately restore the 81 cancelled flights. Aircraft and employees would need to be repositioned before the regular schedule could resume.
Which services are expected to operate?
The threatened stoppage applies to WestJetās mainline flight attendants. WestJet Encore flights operated with Q400 aircraft are expected to continue, as are codeshare flights physically operated by partner airlines.
Passengers should check the āoperated byā line on their itinerary. A booking carrying a WestJet flight number may remain unaffected when another airline is operating the aircraft.
The disruption follows other unrelated problems affecting Canadian travellers, including recent U.S. flight cancellations at Montreal airport. In both situations, checking live flight information is more reliable than relying on the original departure schedule.
Free booking changes are available
Passengers booked to travel between July 30 and August 4 may make one change or cancellation without an additional fee. The option is available through WestJetās Manage Trips service.
The policy does not necessarily eliminate a fare difference if a customer voluntarily selects a more expensive replacement flight. Travellers should review the final price before confirming a change.
Customers who booked through a travel agency must contact the original seller. WestJet Vacations, Sunwing Vacations and Vacances WestJet QuƩbec passengers may receive separate instructions from their package provider.
What happens when WestJet cancels a flight?
Affected passengers may be offered rebooking or a refund. As a large Canadian airline, WestJet generally must arrange another flight within 48 hours for disruptions considered outside its control, using its own service or an airline with which it has a commercial agreement.
If no suitable option is available within that period, broader rebooking requirements may apply. Passengers can request a refund for the unused portion of a ticket when the alternative arrangement no longer meets the purpose of their trip.
Someone stranded during a connection may also qualify for transportation back to the original departure point. Passengers should keep all booking records, cancellation notices and written communication from WestJet.
Cash compensation is not guaranteed
Canadian passenger-protection rules generally treat labour disruptions as outside an airlineās control. Consequently, affected customers may have rebooking or refund rights without qualifying for the fixed cash compensation available for some airline-controlled cancellations.
Coverage for meals, hotels and alternative transportation depends on the circumstances. Travellers should retain itemized receipts and submit claims in writing. Travel insurance or credit-card protection may cover some expenses the airline does not reimburse.
Anyone considering an alternative airport should include ground-travel expenses in the decision, particularly where airport drop-off charges can increase journey costs. Voluntary expenses may not be covered if the original flight remains scheduled.

Why flight attendants may walk out
Compensation for work performed while aircraft are on the ground is a central bargaining issue. Flight attendantsā duties can include boarding passengers, completing safety checks, preparing cabins and assisting travellers during delays.
WestJet says its proposed contract includes duty-premium payments, scheduling improvements, enhanced hotel and travel provisions, and cumulative wage growth of approximately 36% over four years.
CUPE says the offer does not yet resolve all the issues required for a comprehensive agreement. Union president Alia Hussain said progress had been made, but remaining matters needed to be settled at the bargaining table.
Why the disruption could become much larger
WestJet operates more than 600 flights daily and carries over 70,000 passengers on busy days. A full shutdown during peak summer travel could therefore affect far more people than the initial 81 cancellations.
Passengers travelling after August 4 should continue monitoring their bookings even though the current flexible-change policy ends on that date. If a strike or lockout occurs, disruptions could continue after the dispute is resolved while WestJet restores aircraft and crews across its network.
