About Thai Airways
Thai Airways International is the flag carrier of Thailand and one of the founding members of Star Alliance. Its hub is Bangkok Suvarnabhumi Airport. From there the airline flies within Thailand, across Southeast Asia, to China, Japan, Korea and India, and on long-haul routes to Europe and Australia. Bangkok works well as a transfer point between Europe and the rest of Southeast Asia, which is how many agents use the airline. Cabins include Royal Silk business class and Economy, with First class offered on selected aircraft.
Thai Airways can be booked on IATA.co when it is returned by our suppliers. Put differently, Thai Airways fares appear in your search results whenever our flight suppliers offer them for your route and dates. Agents search in the booking portal, and developers get the same live results through the flights API. Tickets are paid for from a prepaid balance. Baggage, change and refund terms belong to the fare, and they are displayed before you confirm.
Thai Airways airline codes explained
Thai Airways uses the two-letter IATA airline code TG and the three-letter ICAO code THA. The IATA code TG is the one shown on tickets, fare displays and booking screens, while the ICAO code THA is used in air traffic control and flight planning.
Thai Airways is a full-service carrier, based in Thailand, operating mainly from Bangkok (BKK). It is a member of Star Alliance.
Booking Thai Airways fares as a travel agent
Travel agents book Thai Airways fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live TG fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Thai Airways results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search Thai Airways (TG) through the flights API
Developers and agencies can run the same Thai Airways search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code TG and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
