WestJet began cancelling flights early Saturday morning after a union representing about 4,400 flight attendants issued a 72-hour strike notice [1].

The disruptions threaten nationwide travel as the airline and the Canadian Union of Public Employees (CUPE) struggle to reach an agreement. A strike would likely paralyze a significant portion of the carrier's operations, leaving thousands of passengers stranded during a peak travel window.

WestJet cancelled 81 flights on the day the strike notice was issued [2]. These preemptive groundings are part of the airline's effort to manage the potential fallout from a work stoppage scheduled for this coming Sunday [2].

The dispute focuses on compensation for work performed while aircraft are on the ground. Flight attendants argue they should be paid for essential duties such as boarding passengers, conducting safety checks, and managing flight delays [1], [3]. Currently, this ground work remains unpaid.

CUPE represents the approximately 4,400 flight attendants involved in the dispute [1]. The union issued the 72-hour notice to signal that a walkout is imminent if the company does not address the compensation issues [1].

Passengers have been advised to monitor their flight status as the deadline approaches. While the airline has not provided a detailed timeline for resolution, the current cancellations suggest a cautious approach to avoid mid-air or tarmac disruptions should the strike begin on Sunday [2].

This labor dispute highlights a growing tension in the aviation industry regarding 'duty time' versus 'pay time.' By grounding flights before a strike officially begins, WestJet is attempting to mitigate the operational chaos of a sudden walkout, but the move also increases immediate pressure on passengers and may accelerate the union's resolve to secure pay for ground-based safety and administrative tasks.
