WestJet and the union representing its flight attendants reached a deal on August 3, 2026, to end a strike that had canceled 615 flights and disrupted travel for tens of thousands of passengers across Canada. The deal, whose details WestJet has not shared, now goes to the flight attendants themselves for a yes-or-no vote. (Reuters, 2026-08-03)

The strike began on August 2, when all 4,287 WestJet flight attendants walked off the job after contract negotiations fell apart. (CBC, 2026-08-03) The union, called the Canadian Union of Public Employees or CUPE, had given the airline 72 hours of advance notice, as required by Canadian law before workers can legally strike. WestJet responded by issuing a lockout notice, which is when an employer tells workers they will not be allowed to work, rather than keeping operations going. WestJet said it did this to keep control of its operations during the dispute. (WestJet, 2026-07-30; WestJet, 2026-08-02)

WestJet canceled 615 flights through Tuesday because of the strike, according to Reuters. (Reuters, 2026-08-02) After the tentative agreement was reached, the airline started bringing back its schedule, though it was expected to take time to get everything running normally again because of how many flights were affected.

The main disagreement was about how flight attendants get paid. Across the airline industry in North America, flight attendants are usually paid only for the hours a plane is actually in the air. They are not paid for the time they spend on the ground preparing the cabin, helping passengers board, or waiting between flights. CUPE wanted flight attendants to be paid from the moment they check in for work until the moment they clock out. That change would reshape how flight attendant pay is calculated from the ground up.

The buildup to the strike started weeks earlier. On July 9, 2026, CUPE started a strike vote among its members, calling it a historic step for WestJet's flight attendants. (CUPE, 2026-07-09) The vote ran through July 15 and gave the union the green light to call a strike if talks failed. The 72-hour notice followed, and when no deal was reached before the deadline, the walkout began.

There is an important detail about how WestJet is organized. WestJet Encore, the airline's smaller regional branch, has a contract with a no-strike clause, meaning its workers agreed not to strike except in certain legal situations. That clause did not apply to the main WestJet operation, where the striking flight attendants work. That left them free to strike once they met the legal requirements. (CUPE Collective Agreement, date unknown)

The broader context here is that Canada's airline industry has seen several strikes and near-strikes in recent years. Both flight attendants and pilots have been pushing for higher pay and better working conditions after inflation ate into their real earnings. The WestJet dispute fits that pattern, but the demand for ground-time pay goes beyond a simple raise. It challenges the basic structure of how flight attendant work is valued and paid for.

For WestJet, the strike tested the airline's ability to handle a disruption at the busiest time of the summer travel season. By issuing a lockout notice alongside the union's strike notice, WestJet chose to manage the shutdown on its own terms rather than let flights be disrupted gradually. The 615 cancellations reflect that choice: a short, sharp interruption rather than a slow decline in service.

The next step is the ratification vote. Union leaders have to present the deal to members who just spent days on a picket line, which can make it harder to convince everyone to accept the agreement. WestJet has not shared the terms, so members and the public will only learn the details when the union presents the deal for a vote. If members vote yes, attention turns to how fast WestJet can get back to normal and whether this deal encourages flight attendants at other Canadian airlines to push for the same ground-time pay.

If members vote no, the strike could start again. Both sides would go back to negotiations under heavy public and political pressure to avoid a second disruption. The federal government chose not to step in with back-to-work legislation, which is a law that forces workers to return to their jobs. That decision stands out because the government has used that tool in some recent Canadian transportation labor disputes.
