Our services may include:

• Flight search and availability information;

• Fare quotation;

• Flight reservation;

• Airline ticket issuance;

• Booking changes and rebooking assistance;

• Cancellation and refund assistance;

• Customer support relating to eligible bookings.

Thai Airways remains responsible for the operation of its flights and for applying its own Conditions of Carriage, fare rules, baggage rules and operational policies.

Where Thai Airways' policies differ from information displayed on our website, the applicable airline policy and the fare rules attached to the passenger's ticket shall prevail.

---

3. Booking Request and Reservation

Submitting a booking request does not necessarily mean that a ticket has been issued.

A booking may remain subject to:

• Flight availability;

• Fare availability;

• Passenger information verification;

• Airline approval;

• Payment confirmation;

• Ticketing deadlines;

• Applicable fare conditions.

A reservation is considered confirmed by us only when the applicable booking and payment process has been completed and the passenger has received the relevant confirmation or ticket information.

---

4. Ticket Issuance

Once payment has been successfully received and the booking conditions have been satisfied, we will process the ticket issuance.

Depending on the itinerary, the passenger may receive:

• Airline Passenger Name Record (PNR);

• E-ticket number;

• Flight itinerary;

• Fare information;

• Applicable baggage allowance;

• Other relevant booking information.

Passengers should carefully review all information immediately after receiving the ticket.

This includes:

• Passenger name;

• Date of birth, where applicable;

• Flight dates;

• Flight numbers;

• Departure and arrival airports;

• Travel dates and times;

• Baggage allowance;

• Fare conditions.

Any error should be reported to us immediately.

5. Passenger Name and Personal Information

Passengers are responsible for providing accurate information at the time of booking.

The passenger name must correspond with the passenger's valid travel document.

Depending on Thai Airways' policies and the applicable fare type:

• Name changes to another person may not be permitted;

• Minor spelling corrections may be permitted;

• Name corrections may be subject to airline approval and fees;

• Some promotional or restricted fares may not permit name correction.

A name correction is not the same as transferring a ticket to another passenger.

Thai Airways' applicable name policy and the fare rules attached to the ticket shall determine whether a correction can be processed.

---

6. Prices, Taxes and Service Fees

The total price displayed before payment may include:

• Base airfare;

• Government and airport taxes;

• Airline-imposed charges;

• Applicable service or booking fees.

Where applicable, our service fee is separate from the airline's fare and is charged for the services provided by our travel agency.

The final amount payable will be displayed or communicated before payment is completed.

Airline fares are subject to availability and may change before ticket issuance.

A fare shown during a search is not guaranteed until the booking has been confirmed and the ticket has been issued.

---

7. Payment

Payment must be completed within the applicable ticketing deadline.

If payment is not received within the required time:

• The reservation may expire;

• The fare may no longer be available;

• The booking may need to be recreated;

• A different fare may apply.

A payment confirmation does not automatically guarantee ticket issuance if the payment has not been successfully verified or if the airline's ticketing conditions have not been satisfied.

---

8. Fare Rules

Every Thai Airways ticket is subject to specific fare conditions.

Fare conditions may determine:

• Whether changes are permitted;

• Change fees;

• Fare differences;

• Cancellation eligibility;

• Refund fees;

• No-show conditions;

• Name correction rules;

• Route or flight restrictions;

• Minimum or maximum stay requirements;

9. Flight Changes and Rebooking

A request to change a ticket is subject to Thai Airways' applicable policies and fare conditions.

Where changes are permitted, the total cost may include:

Change Fee + Fare Difference + Tax/Fee Difference + Applicable Service Fee

The passenger may only change the flight if the applicable fare rules permit such change.

A change to a lower-priced fare may not necessarily result in a refund of the fare difference.

Some fares may only permit changes to the same or higher booking class.

All changes are subject to seat and fare availability.

---

10. Cancellation and Refund

Cancellation and refund eligibility depends on the fare conditions of the ticket.

Some fares may be:

• Fully refundable;

• Refundable subject to a cancellation fee;

• Partially refundable;

• Non-refundable.

Where a refund is permitted, the amount refunded may be reduced by:

• Airline cancellation/refund fee;

• No-show fee, where applicable;

• Non-refundable taxes or charges;

• Ticketing or service fees;

• Other applicable deductions under the fare rules.

Ticketing or service fees charged by https://flythaismiles.com may be non-refundable unless otherwise stated.

11. Cancellation Shortly After Ticket Issuance

Where permitted by the applicable fare and airline rules, customers may request cancellation shortly after ticket issuance.

For eligible requests, the cancellation request should normally be submitted:

On the ticket issuance date and before 23:00 Vietnam Time (GMT+7).

Cancellation within this period does not automatically guarantee a full refund.

Applicable airline rules, fare conditions, taxes, ticketing fees and service fees will still apply.

The exact refund amount will be advised after the ticket conditions have been reviewed.

---

12. No-Show

A passenger is considered a no-show when the passenger does not travel and does not complete the required cancellation or change procedure within the applicable airline's permitted time.

No-show may result in:

• Additional no-show fees;

• Loss of the ticket value;

• Loss of onward or return sectors;

• Restrictions on subsequent changes or refunds.

Thai Airways may automatically cancel remaining sectors after a passenger fails to board a flight, subject to its applicable policies.

Passengers should therefore contact us or the airline before the scheduled departure time if they are unable to travel.

---

13. Combination and Mixed Fare Tickets

An itinerary may contain different fare types or booking classes.

Where multiple fare types are combined, the most restrictive applicable fare condition may affect the ticket.

Certain promotional fares may not be combined with other fare types for cancellation or refund purposes.

The applicable conditions will be determined by the airline's fare construction and the rules attached to the ticket.

---

14. Promotional and Special Fares

Promotional fares may have additional restrictions.

These may include:

• Non-refundable conditions;

• Restricted changes;

• Higher change fees;

• No-show penalties;

• Limited baggage allowance;

• Restricted name correction;

Promotional fares should not be assumed to have the same conditions as standard fares.

The conditions displayed or attached to the ticket shall prevail.

---

Baggage allowance depends on:

• Fare type;

• Cabin class;

• Route;

• Ticket conditions;

• Applicable Thai Airways baggage policies.

The baggage allowance shown on the passenger's confirmed ticket or booking record shall prevail.
