Air Canada is launching a new service notifying passengers by email or a text message to their mobile phone when their flights are cancelled or delayed.
Passengers disrupted by storms or other problems will be able to rebook flights using their computer or mobile device, avoiding the need to line up or contact agents.
The airline says passengers will be notified automatically, offered alternative flights or the ability to choose another flight and be allowed to cancel trips altogether.
Chief operating officer Duncan Dee says the airline wants to use mobile phones and smartphones to improve communications with its customers.
Those without electronic addresses will be routed to call centres.
