I had a flight from Geneva to Montreal scheduled for Sunday, July 7 (AC831) which was delayed, delayed, and delayed, and then cancelled. We got a meal voucher while waiting at the airport and later, when the flight was cancelled, we got a hotel room with dinner and breakfast for the next morning. We all left the next day, about 22 hours later (AC2031). Is there anything else I can get as compensation? As a minimum, isn't Air Canada supposed to pay for international phone calls I had to make while stuck in Geneva? If there is anything I can claim, how should I proceed? Thank you for any pieces of advice.
