Thai Airways Cancellation Policy already offers the most generous change and cancellation policies in the airline industry. As long as you change your ticket ten minutes before flight time, you can get your flight re-booked or refunded into travel credit without penalty. You’ll just have to pay any fare difference that applies when you re-book your flight. Note that travel funds are good for one year from original departure date and must be used by the person whose name is listed on the ticket.
