WestJet flight attendants issue 72-hour strike notice as lockout looms

WestJet and its flight attendants are heading toward a tense showdown after the union representing thousands of cabin crew served a 72-hour strike notice, prompting the Calgary-based airline to issue a corresponding lockout notice and warn of significant disruptions to its network as early as the busy August long weekend.

Strike notice sets up early August travel uncertainty

Publicly available information indicates that the Canadian Union of Public Employees local representing more than 4,000 WestJet flight attendants delivered formal notice on July 30 that its members are prepared to begin strike action in 72 hours. Under federal labour rules, a legal work stoppage by either side can occur only after such a notice period, following a mandatory cooling-off phase.

WestJet, one of Canada’s largest carriers, responded by issuing its own 72-hour lockout notice to cabin crew. A lockout would allow the airline to halt work by unionized flight attendants and begin cancelling or consolidating flights in advance, rather than waiting for employees to walk off the job.

The duelling notices mean that, unless a last-minute settlement is reached, service could be curtailed as early as the first weekend of August, a peak period for domestic holidaymakers and transatlantic travelers. Previous labour disputes at Canadian airlines suggest carriers often begin ramping down schedules before an actual strike or lockout start time in order to avoid aircraft and crews being stranded away from their bases.

Travel forums and social media discussions already show passengers weighing backup options, including fully refundable tickets on rival airlines and flexible hotel reservations, in case flights operated by WestJet mainline or its affiliates are affected.

Dispute centers on pay, unpaid time and working conditions

According to recent union communications and published commentary, WestJet flight attendants are seeking improvements to wages, scheduling rules and what they describe as extensive unpaid work built into their duties. Cabin crew typically are not paid their full hourly flight rate during boarding, deplaning and many ground-based tasks, despite being responsible for safety and customer service throughout that time.

The WestJet dispute follows a broader trend in North American aviation, where cabin-crew unions at multiple carriers have focused on compensation for unpaid duties as a central bargaining issue. Observers note that the 2025 Air Canada flight attendants’ strike and recent contract settlements for pilots and mechanics have helped set new benchmarks for pay and work rules in the Canadian market.

Public reports indicate the WestJet union secured a strong strike mandate earlier in July, with a large majority of voting members authorizing job action if negotiations failed. Union messaging has framed the vote and subsequent notice as an attempt to force the airline to recognize the full scope of cabin crew responsibilities and align compensation more closely with industry peers.

WestJet has publicly positioned itself as a value-focused or budget-oriented carrier and has argued in past labour disputes that significant cost increases could threaten its competitive model. Analysts say that tension is now playing out again, as the airline tries to contain labour costs while facing a workforce that believes it is underpaid relative to both domestic rivals and international competitors.

Airline prepares for lockout and potential wide-scale cancellations

By serving a lockout notice in response to the strike notice, WestJet has signalled that it is prepared to take the initiative in managing any work stoppage. Industry analysts note that this approach allows an airline to wind down operations in a controlled way rather than reacting suddenly to flight attendants walking off the job.

During a similar episode involving WestJet pilots in 2023 and aircraft mechanics in 2024, the carrier preemptively cancelled hundreds of flights as negotiations reached critical stages. Court filings and regulatory documents from those periods show that WestJet typically begins reducing its schedule ahead of a potential strike date, parks parts of its fleet at key hubs such as Calgary and Toronto, and prioritizes repatriating aircraft and crews from overseas destinations.

Based on that recent history, observers expect WestJet to trim its network in the days leading up to any effective strike or lockout time, focusing remaining capacity on core domestic routes and essential transcontinental services. Leisure routes and secondary regional connections are considered more vulnerable to short-notice cuts.

Passengers booked to travel between late July and the first week of August are being encouraged, in public advisories and online discussions, to monitor their reservations closely and review airline policies for voluntary changes or cancellations. WestJet has already issued flexible booking options around the potential disruption window in past disputes, and similar measures are anticipated if talks remain unresolved.

Rules for strikes, lockouts and passenger protections

The WestJet standoff is governed by the Canada Labour Code, which sets out the framework for legal strikes and lockouts in federally regulated sectors such as aviation. After conciliation and a cooling-off period, either side may serve a 72-hour notice of intent to initiate a work stoppage. Once that window expires, a strike or lockout can begin at any time, though the parties often continue negotiating right up to the deadline.

Legal filings and previous Canadian industrial-relations cases show that employers may treat flight cancellations that stem from their own lockout decisions as within their control, in contrast to some interpretations of passenger rights during unforeseen safety or weather events. That distinction can influence whether travelers are entitled to compensation or only to rebooking and refunds under the federal Air Passenger Protection Regulations.

Advocacy groups have argued in past WestJet disputes that large-scale cancellations announced days in advance of a labour deadline should generally be considered within the airline’s control, since they are a direct result of management decisions about how to handle negotiations. Airlines have countered that they are responding to the threat of a work stoppage and prioritizing safety and predictability for customers.

The current WestJet situation is likely to renew scrutiny of how labour disruptions are handled under Canada’s consumer-protection framework, particularly if passengers face last-minute cancellations during one of the busiest travel periods of the year.

What travelers should watch in the coming days

For now, WestJet flights continue to operate, and both sides remain under pressure to reach an agreement before the strike and lockout clocks run out. Historically, Canadian airline labour disputes have often been resolved in the final hours, either through direct bargaining or with the assistance of federal mediators.

Travel-industry analysts suggest that the next 24 to 48 hours will be critical. Signs that negotiators are making progress, such as announcements of intensive bargaining sessions or reference to a framework for a tentative deal, could reduce the likelihood of widespread cancellations. Conversely, indications that talks have stalled may prompt the airline to accelerate schedule cuts and encourage passengers to adjust travel plans.

Passengers planning trips over the early August period are being advised, in publicly available guidance, to confirm their contact information in airline reservations, download carrier apps for real-time notifications and consider travel insurance that covers labour disruptions. Those with critical travel, such as cruises or long-haul connections, may opt for alternative routings that avoid potential pinch points in WestJet’s network.

With both a strike and a lockout now legally possible, the coming days are set to test not only WestJet’s relationship with its cabin crew but also the resilience of Canada’s already stretched summer air-travel system.
