Thai Airways cancellation fee policy can be complicated for passengers who are seeking to cancel or change their flight plans. The airline charges fees based on the type of fare purchased and the time frame in which a cancellation is made. For example, if a passenger has purchased a refundable ticket, they may be able to cancel without a fee up until 24 hours prior to departure. Non-refundable tickets will incur a flat fee for cancellations made within the first 24 hours after booking, and then additional fees as departure date approaches. If a passenger misses their flight entirely, Thai Airways will charge both a no-show fee and require the purchase of a new ticket for future travel. Understanding this complex policy is important for travellers hoping to avoid additional fees or penalties when cancelling their bookings with Thai Airways.
