WestJet flight attendants could begin a strike as early as Sunday, July 31, 2026 [1], following a breakdown in contract negotiations.

A work stoppage by the crew would disrupt travel across WestJet’s entire Canadian network. Because flight attendants are essential for aircraft safety and takeoff, a strike would likely force the airline to cancel a significant number of flights during the peak summer travel season.

The union representing approximately 4,400 flight attendants [3] is preparing for the possibility of a strike. The dispute centers on wages and allegations of unpaid work during the negotiation process [2].

Flight attendants have signed a wind-down plan to manage the transition toward a potential stoppage [3]. This preparation ensures that the union is legally and operationally ready to cease work if a new agreement is not reached by the deadline.

WestJet has not provided a public timeline for a resolution, but the potential for a strike this weekend remains high [1, 2]. The union continues to seek terms that address the financial grievances of its members before the Sunday deadline [2].

WestJet flight attendants could strike as early as Sunday, July 31, 2026.

A strike at this juncture would create a cascading effect on Canadian aviation, as July is one of the busiest months for domestic and international travel. If the union and WestJet cannot reach an agreement, the airline faces significant revenue loss and a backlog of stranded passengers, while the union leverages the peak travel window to secure higher wages.
