Here Is a Compressive Guide to help you

 Thai Airways' flight change policy +1–844||765||2010 allows free flight changes only within a 24-hour grace period, after which you may have to pay a flight change fee to make any changes. When making changes to your flight, you will also have to pay the difference between the old and new fares, taxes and surcharges. Some important things to remember about Thai Airways' flight change policy is that you can make flight changes online only if you bought your ticket directly through the airline's website or mobile app, and tickets bought through a travel agent can only be changed through them.

If you have a flight booked with Thai Airways and need to make a change to your itinerary, it is important to understand the airline's flight change policy. Here's a guide on how to change your Thai Airways flight ticket, as well as information on their flight change policy, charges and date change policy.

Thai Airways Flight Change Policy

Thai Airways allows passengers to make changes to their flight bookings, subject to the fare rules and conditions of the ticket purchased. Specific terms and conditions may vary depending on fare type, destination and availability. It is recommended that you check the fare rules or contact Thai Airways directly for the most accurate and up-to-date information on their flight change policy.

Thai Airways passengers can keep their ticket value for up to two years (from the date of booking) to rebook the flight at a later date.

Purchased tickets can be redeemed for travel credit. In such cases, Thai Airways offers an additional bonus of 10%. When rebooking a flight, passengers can change the date and destination of the flight without restriction.

Thai Airways also allows the departure city to be changed when booking as long as the change is made in the same country as the original booking.

Below are the major highlights of Thai Airways change flight policy:

You have the right to a full refund if Thai Airways changes the time of your flight significantly, the time is unacceptable to you and you cannot be booked on a flight that suits you.
