Cancelled flight? Airlines must refund you, and you can file a claim

Passengers whose flights are cancelled are entitled to a refund from the airline, and the process for claiming it has been outlined. The rules are intended to protect travellers who are left out of pocket when a scheduled service does not operate. Passengers are advised to keep records of their booking and any communication with the carrier. Where a refund is not paid promptly, travellers can pursue a claim through the airline's grievance channels.
