A Calgary man has set off a debate on Twitter about Air Canada's voucher-transfer policy after discovering that he wouldn't be able to transfer a voucher for a flight to his wife since they don't share the same last name.

In an email to The Canadian Press, Air Canada said they allow the transfer of vouchers to anyone they wish, but not all transfers can be done over the phone, as Turner was attempting to do. Documents must be provided in order to avoid fraudulent use, the airline says.
