My husband and I were traveling on an extensive itinerary from Phoenix-Sydney-Hobart-Singapore-Hanoi-Ho Chi Minh City-Phoenix when I was hospitalized for a week in Singapore with pneumonia and other issues, and after discharge flew back to the U.S. from Singapore with a medical escort. This curtailed our plans to continue on with our Vietnam tour and the return flight from Ho Chi Minh City to Phoenix on Air Canada about 2 weeks later. We attempted but were unable to reach Air Canada from Singapore to cancel the return flight. After we returned home, we contacted Air Canada customer service last April regarding a refund of all or part of the $11,750 for my and my husband's airfares. They only refunded several hundred dollars in taxes and the case was closed by customer service without further action. After several more unsuccessful requests, in October we mailed an extensive packet of documentation directly to Air Canada's Calgary Customer Service Headquarters asking them to re-open the case, but again received an email saying that, while unfortunate, the medical emergency did not constitute grounds for reimbursement of a non-refundable ticket. Since we booked the final return flight directly with Air Canada, it was not covered under our travel insurance policy. However, it is a significant amount of money, and we feel that they should at least be open to negotiating a partial refund due to the medical emergency. Since my and my husband's current health conditions will not allow for future air travel, a voucher would not be an acceptable resolution. We feel that Air Canada has taken a very hard line in this case, given the circumstances of the hospitalization and our attempt to cancel. We are wondering if anyone else has had success in approaching Air Canada with a similar situation. Sharon S.
