You’re allowed to take at least 2 checked-in bags on international Thai Airways International flights. Weight and size restrictions may vary based on your cabin class or even the size of the aircraft. Read through your
Thai Airways International itinerary or get in touch with Thai Airways International customer service to find out what rules apply to your booking. As a guideline, each bag should not exceed 62 in total in dimension and 50 lb in weight. If you need to bring more, purchase extra checked baggage before you fly. This is usually cheaper than paying for excess at the airport.
