In 2026, a flight travel voucher is a form of digital credit issued by an airline, typically as compensation for a flight cancellation, delay, or as a refund for a voluntary booking change. A major regulatory update on March 26, 2026, changed how these are handled: airlines are now prohibited from issuing vouchers "by default" and must obtain explicit passenger consent before providing a credit instead of a cash refund. Vouchers usually have an expiration date (often 12 to 24 months) and are linked to the original passenger's name. In 2026, many major carriers have introduced "flexible" vouchers that can be used for any destination in their network and can even be converted back into cash if they remain unused for a certain period, following consumer protection laws in the EU and North America. They serve as a financial placeholder, allowing travelers to rebook future travel without losing the value of their original purchase, provided they adhere to the airline's specific redemption terms and blackout dates.
