Air Canada is preparing to halt the majority of its flights for at least three days after failing to reach a new contract agreement with its flight attendants’ union, a move that could disrupt travel

for around 130,000 passengers each day.

The Canadian Union of Public Employees, representing Air Canada’s flight attendants, issued a formal strike notice following stalled negotiations over wages and other compensation. The union rejected the airline’s proposal to extend talks through arbitration.

In response, Air Canada announced it would begin a “phased wind down” of operations to limit disruption, though it warned that many travelers may still be stranded. The first wave of cancellations will begin August 14, with more on August 15, and a complete halt of flights operated by Air Canada and Air Canada Rouge scheduled for August 16. Regional affiliates Jazz and PAL, which handle about 20% of the airline’s capacity, will continue operating as normal.

Passenger Impact

The suspension could leave thousands of travelers stuck, including 25,000 Canadians returning from abroad each day. Customers whose flights are canceled will be eligible for full refunds or alternate travel arrangements, but space on other carriers will be limited during the busy summer season.

Air Canada said it is working with Canadian and international airlines to secure alternate flights for stranded passengers, though finding seats may take time.

Effect on U.S. Travelers

While Air Canada does not fly domestic routes within the United States, the carrier plays a significant role in connecting U.S. passengers to Canada and beyond. Travelers with upcoming trips through Canadian hubs — including connections to Europe, Asia, and other destinations — should monitor flight notifications closely.

The strike could also have ripple effects for other airlines. United Airlines, a close partner of Air Canada through the Star Alliance network, may see higher demand on international and cross-border routes as it takes on displaced passengers.
