Thai Airways International is Thailand's national airline and flies under the International Air Transport Association (IATA) code TG. The airline's Thailand page lists Bangkok and eight other Thai destinations; its check-in guidance directs passengers to Bangkok Suvarnabhumi Airport (BKK). It left court-supervised business rehabilitation in June 2025 and its shares have traded on the Stock Exchange of Thailand again since 4 August 2025.

Where Thai Airways flies inside Thailand

The airline's own Thailand page names Bangkok and eight other destinations in the country. This site has route pages for each Bangkok pair:

• Bangkok to Chiang Mai
• Bangkok to Chiang Rai
• Bangkok to Hat Yai
• Bangkok to Khon Kaen
• Bangkok to Krabi
• Bangkok to Phuket
• Bangkok to Ubon Ratchathani
• Bangkok to Udon Thani

Bangkok has two airports and they are not interchangeable. Thai Airways moved its operations base from Bangkok Don Muang Airport (DMK) to Bangkok Suvarnabhumi Airport on 28 September 2006.

The network looks like this because of Thai Smile, the wholly owned subsidiary that flew Airbus A320s under the code WE. Its operations transferred to Thai Airways, which relaunched eight of Thai Smile's nine domestic routes under TG, and Thai Smile registered its dissolution on 5 June 2025.

The aircraft on a domestic flight

Thai Airways reported a fleet of 80 aircraft as of 31 March 2026 in its first-quarter results. The type a domestic passenger is most likely to be on is the Airbus A320-200, which the airline describes as serving domestic and regional routes: 20 aircraft, 156 seats made up of 12 in Royal Silk Class and 144 in Economy.

The amenities the airline lists for that type are a baby bassinet and a stowage compartment. It does not list an in-seat display or a power outlet, so charge your phone before you board and bring something to read.

Baggage on a Thai Airways domestic flight

Thai Airways changed the way it measures domestic checked baggage for travel from 2 March 2026. Sectors inside Thailand now run on a piece allowance, so what you get is one bag at a set weight rather than a total number of kilos to split between bags.

Thai Airways announced the piece figures for sales and ticket issuance from 25 November 2025, including reissuance of totally unused tickets, where travel commences on or after 2 March 2026. The older weight table is still displayed alongside the new one on the airline's own checked baggage page, so check which set applies to your ticket before you book.

Cabin	Checked allowance	Maximum size
Royal Silk Class	1 piece, 32 kg	158 cm
Premium Economy Plus	1 piece, 32 kg	158 cm
Premium Economy	1 piece, 23 kg	158 cm
Economy, every fare family	1 piece, 23 kg	158 cm

The 158 cm is height plus width plus length added together, counting the wheels and the handles. Where a journey mixes cabins, the airline sets the allowance by the highest class of service the fare was paid in. An infant not occupying a seat gets one piece at the weight of the accompanying adult's class.

This is the change to watch if you have flown Thai Airways before. An Economy Flexi or Full Flex ticket carried a 30 kg weight allowance under the old domestic rules and now carries a single piece of 23 kg. Packing from memory will get you a different answer at the desk.

Cabin baggage is one piece of up to 7 kg in every class, at a maximum 56 cm by 45 cm by 25 cm including wheels, handles and side pockets. A handbag, a laptop of up to 75 cm total and 1.5 kg, walking sticks or crutches and infant food travel free on top of that.

The 7 kg limit gets enforced in practice: Thai Airways states that a spot check may be performed against the test unit or the weighing machine at the check-in counter or at the boarding gate. A bag that clears the counter can still be weighed again at the gate.

How do I check in to a Thai Airways flight?

Online check-in opens 24 hours before departure and closes one hour before it. These are the windows the airline currently publishes:

• Online check-in: opens 24 hours before departure, closes 1 hour before.
• Checked bags: in at least 60 minutes before the flight.
• Check-in counter: closes 40 minutes before a domestic departure, and 50 minutes before an international one.
• Boarding gate: closes 10 minutes before departure, on domestic and international flights alike.

At Suvarnabhumi the self-service bag drop is at rows D to E on the fourth floor.

A counter that shuts 40 minutes before a domestic departure is easy to misjudge, and the bag drop and the gate are two further deadlines rather than the same one. The airline publishes them all on its check-in page.

Still the national airline, no longer a state enterprise

Thai Airways still describes itself as the national airline of Thailand on its own company profile. What changed on 22 May 2020 was who owns it: the Ministry of Finance sold 3.2 per cent to Vayupak Fund 1, its own holding fell to 47.9 per cent, and the airline's timeline records that "the Company is not a state enterprise" as a result. Being the national airline is a description of the role it plays, while being a state enterprise was a matter of who held the shares, and losing the second did not change the first.

Thai Airways co-founded Star Alliance on 14 May 1997 with Air Canada, Lufthansa, Scandinavian Airlines System and United Airlines, and it remains a member.

Did Thai Airways go bankrupt?

Thai Airways entered court-supervised business rehabilitation in 2020 and left it on 16 June 2025, when the Central Bankruptcy Court ordered the process terminated. The company had filed the petition on 26 May 2020, citing the effects of COVID-19, lost revenue and insufficient liquidity, and the court ordered the rehabilitation on 14 September 2020 and approved the plan on 15 June 2021.

When the process ended, the authority of the Plan Administrators ceased and the board of directors resumed full authority. Trading in the shares resumed on the Stock Exchange of Thailand on 4 August 2025. In the first quarter of 2026 the airline carried 4.18 million passengers, filled an average of 83.1 per cent of its seats, and reported a net profit of 10,107 million baht.

How does Royal Orchid Plus status work with Thai Airways?

Royal Orchid Plus (ROP) has four tiers: Member, which the airline also calls Silk, then Silver, Gold and Platinum. Member is the entry tier, enrolment in it is free, and there are 2,500 bonus miles after a first Thai Airways flight.

Silver comes at 10,000 Qualifying Miles within 12 rolling months, or 15,000 within 24. Gold comes at 50,000 within 12 rolling months or 80,000 within 24, or at 40 international sectors flown on Thai Airways within 12 rolling months, excluding the T, K, S, G, V, W and L booking classes.

Qualifying Miles are miles actually flown on a paid fare on Thai Airways and Star Alliance operated flights, including the class of service bonus. Bonus, promotional and partner miles are excluded from the membership evaluation, so miles that arrive without a flight behind them do not move you up a tier. Miles are valid for three years.

Two programme changes are running at the moment. The new qualification criteria due to take effect on 5 August 2026 have been postponed, and the current ones continue to apply. Gold and Platinum status expiring between 1 June and 31 December 2026 has been extended to 30 June 2027.
