WestJet and the Canadian Union of Public Employees (CUP) Local 8125 reached a tentative agreement Monday to end a flight-attendants strike [1].

The resolution prevents further prolonged disruptions to Canadian air travel during a critical period for passengers and airline operations.

The strike lasted 28 hours [1] before the two parties settled the labor dispute over contract terms. The work stoppage caused hundreds of flight cancellations [2] and left thousands of passengers stranded across Canada [2].

Flights began resuming from major hubs, including Toronto’s Pearson International Airport [1]. While the tentative deal provides a path forward, the immediate timeline for the full restoration of all scheduled services remained a point of variation in early reports [3].

The dispute centered on contract terms between the airline and the union representing its flight attendants. The sudden grounding of aircraft created a logistical bottleneck at Canadian airports, forcing the company to manage a massive backlog of displaced travelers [2].

WestJet and the union have not yet released the specific financial terms of the agreement. The tentative nature of the deal means it must still be ratified by union members before becoming a formal contract [3].

The strike lasted 28 hours before the two parties settled the labor dispute.

This agreement stabilizes WestJet's operational capacity after a brief but high-impact disruption. The scale of the cancellations relative to the strike's short duration highlights the fragility of current aviation scheduling and the significant leverage held by flight-crew unions in the Canadian transport sector.
