Thai Airways cancellation policy

Tickets across most fare types, including Royal Silk, can be cancelled for a full refund within 24 hours of booking provided departure is 7+ days away, though the lowest promotional fares may be excluded. After that window, a cancellation fee applies based on fare rules, and refunds typically take up to about 20 business days.

Open Manage Booking or contact the original booking channel and review the itemised refund before confirming. The final amount depends on fare rules, timing, taxes, add-ons and used sectors.

Often yes, subject to the fare's change fee and any fare difference. Compare the total change cost with the cancellation loss before deciding.

Airline-initiated disruption can create rebooking or refund choices that differ from voluntary cancellation. Review the options in the airline notification or Manage Booking.
