If the ticket is not used then the fee is the same as the fee paid. On the other hand, if the ticket is used then the refund is equal to the difference between the fare paid and the fare applicable for the carriage/service used. The airline will only refund the unused portion of the ticket. In addition,Luxair Airlines Cancellation Policy says the airline will return the ticket to the person named on the ticket or the person who paid for the ticket, if satisfactory proof of payment is provided. https://www.cancelation-policy.com/luxair-cancellation-policy
