Cancellation Policy
Review cancellation guidance and open the official airline page.
Thai Airways
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.
We summarize Thai Airways's own published cancellation policy. Airlines change fees, allowances and document rules without notice, so always confirm the latest details on the official page linked below before you travel.
