TG Airline Code: Thai Airways IATA & ICAO
Thai Airways is stored in this dataset as IATA code TG and ICAO code THA, based in Thailand. GDS segment lines print the IATA code before the flight number. Live routes, fares and baggage policies are not in this dataset.
Overview
TG is the IATA airline designator stored for Thai Airways. ICAO is THA. Country of record: Thailand. On a cryptic GDS line the IATA code sits immediately before the flight number, for example TG 456. Agents should not confuse TG (two characters, sometimes a digit such as 6E) with THA (three letters). This code page does not list routes, alliances, baggage rules, or fleet. Those facts are not in the dataset. Other Thailand carriers stored here: FD (Thai AirAsia). To decode a full itinerary that markets TG, paste the PNR into the parser.
How to use this page
- Find TG at the start of the flight line in the PNR.
- Paste the full itinerary into the PNR parser (or the GDS-specific parser if you know the host).
- Confirm the carrier name resolves to Thai Airways.
- Do not add baggage or meal claims that the PNR did not print.
Example
Example segment: 2 TG 456 H 26OCT 5 WLGAKL HK1 1945 2050 The parser should set marketing carrier TG (Thai Airways) and flight 456. Class H is a fare bucket, not proof of cabin without the booking-class tool.
