Thousands of Air Canada flyers are facing another day of travel disruption on Monday, after striking Air Canada flight attendants defied a federal back-to-work order and abruptly halted the airline's plans to resume operations.

Air Canada has announced it will suspend all flights through Tuesday afternoon after flight attendants still defy a federal back-to-work order.

Instead, the Montreal-based airline said it now plans to resume flights on Monday evening, despite executives with the Canadian Union of Public Employees insisting that they have no intention of ending the walkout, which began early Saturday, without a negotiated collective agreement.
