Thank you for pointing out the clarity of what BA is doing with their "ticket" - now if that BA customer incorrectly referred to it as a "voucher" would that clarify the situation here?
AC rule for a 239.00CAD Tango fare:
- Tickets are non-refundable and non-transferable.
- Flights can only be used in sequence from the place of departure specified on the itinerary.
- Customers who no-show their flight will forfeit the fare paid.
- Same-day standby is not permitted.
- Change fee per direction, per passenger, is $75 CAD plus applicable taxes and any additional fare difference.
- Airport same-day changes are subject to availability and are permitted only for same-day flights at a fee of $150 CAD/USD per direction, per passenger, except for passengers travelling on a flight between Toronto and Montreal, or Toronto and Ottawa (connecting flights excluded), for whom the flat fee is $75 CAD/USD. Same-day flights only.
- Changes can be made up to 2 hours prior to departure. Cancellations can be made up to 45 minutes prior to departure. Provided the original booking is cancelled prior to the original flight departure, the value of the unused ticket can be applied within a one year period from date of issue of the original tickets to the value of a new ticket subject to the change fee per direction, per passenger, plus applicable taxes and any additional fare difference, subject to availability and advance purchase requirements. The new outbound travel date must commence within a one year period from the original date of ticket issuance. If the fare for the new journey is lower, any residual amount will be forfeited.
- Read complete fare rules applicable to this fare.
Here is what is presented 3 times during the purchase process, printed with the purchase receipt and itinerary. This person does not have a "voucher" - tickets are not turned into vouchers when they are not used. If you still persist in clinging on the "incorrect reference to a voucher" there is no sense continuing.
