Air Canada has suspended plans to restart operations after the union representing 10,000 flight attendants decided to defy a return-to-work order.

The decision by the union representing the 10,000 workers means that travel chaos will continue for at least a second day. Air Canada said it had suspended its reopening plan until Monday evening.

Air Canada flight attendants defied a government order to end their strike, forcing cancellation of 240 flights and stranding over 100,000 passengers nationwide.
