Trang Airport (TST) is a single-runway airport in Trang province, in southern Thailand, run by the Department of Airports. It has one scheduled route, and it is to Bangkok Don Mueang Airport (DMK). A new passenger terminal had its soft opening in September 2025, and a runway extension is reported as due to finish in 2028.
Thailand's aeronautical information publication puts the field 7 km south of Trang.
The same publication lists the ground transport at the airport as limousines, bus and taxi. Those are the only options it records.
Trang's new passenger terminal had a soft opening on 5 September 2025, with the domestic zone going first and Thai AirAsia, Thai Lion Air and Nok Air all operating that day. The week before, the building was tested with a simulation of about 50 trial passengers. It had been late for years: reports of the opening described the delay as over four years.
It is a big building for the traffic it takes. Reporting of the opening put it at more than 30,000 square metres, and both that reporting and the Department of Airports' own project description give it parking for 700 cars.
Published capacity figures do not agree. The Department of Airports project description gives the new terminal 1,200 passengers an hour, about 3.4 million a year, and attaches a lower figure of 600 an hour to a separate extension of the older building. Some English reporting of the opening attached that 600 figure to the new terminal.
On the afternoon of 7 May 2026 heavy rain came through the new terminal's ceiling and spread across the floor, and part of the ceiling near Exit 2 later collapsed. Services were back to normal the same day.
The Department of Airports' flight board for Trang and its published traffic returns name the same carriers: Thai Lion Air, Nok Air and Thai AirAsia. In the operator's returns for 2024, 2025 and the first seven months of 2026, Don Mueang is the only city listed against Trang.
Thai AirAsia suspended nine domestic routes from Bangkok Suvarnabhumi between 15 July and 30 September 2026 and moved them to Don Mueang. Trang was not one of the nine.
If your onward flight leaves from Suvarnabhumi, you have to cross Bangkok on the ground between the two airports. The guide to transfers between Suvarnabhumi and Don Mueang covers what that involves.
The schedule and the booking form for the route sit on the Bangkok to Trang and Trang to Bangkok pages.
Trang handled 552,626 passengers in 2025, down from 559,844 in 2024, on the Department of Airports' own commercial traffic returns. The first seven months of 2026 came to 305,848 passengers against 318,362 in the same months of 2025, a fall of about 4 per cent. On passenger numbers this is a shrinking airport rather than a growing one.

|---|---|---|
| Calendar 2024 | 559,844 | 3,628 |

June was the quietest month of 2025, and the quietest of the seven months published for 2026. The busiest was March in 2025, and April so far in 2026. June 2026 ran about 40 per cent below April 2026.
Set beside that, the new terminal is built a long way ahead of demand. The 3.4 million passengers a year the Department of Airports attaches to it is roughly six times what Trang carried in 2025.
A project to extend the runway to 2,990 metres and upgrade the airfield electrical system was reported in September 2025 as due for completion in 2028, which would let wide-body aircraft use Trang. As of May 2025 the runway work was reported 37 per cent complete, with the land expropriation at 51 per cent.
Listings and press reports often call the airport Trang International Airport. Thailand's aeronautical information publication names it simply Trang, and lists customs and immigration as available on request.
Trang has been a customs aerodrome since 5 March 1999, which is a smaller thing than a scheduled international gateway. The operator's international traffic tables for Trang read zero for 2024, 2025 and the first seven months of 2026.
A deputy transport minister was quoted in March 2025 saying the aim is for Trang to become an international airport. On the operator's own figures that has not happened yet, so for now an international connection out of Trang means a domestic flight to Don Mueang and a transfer across Bangkok.
