Travel Voucher, also known as Travel Credit, Credit Voucher, or Credit Shell, are vouchers issued by your airline as a refund for your flight ticket. You can use your travel vouchers to purchase future flights from the same airline, in accordance with the airline’s policy. 

Please note that every airline may have different policies and expiration dates for your vouchers. However, in general, travel vouchers are non-transferable, and can be used for multiple transactions with the airline until your credit is used up.
