Generally, if both journeys were issued on the same ticket, and one of them is not used, the other flight is automatically cancelled.

That means: if you don't use your outbound flight ticket to get to your destiny, the airline will automatically cancel your return seat, and if you do use your flight ticket to get to your destiny but you don't use your return seat, you will not be able to claim for a reimbursement.

If you are not planning to use one/both flight seats, you must inform us prior to departure.
