One-Two-GO Airlines

Updated 12th Aug 2026

One-Two-GO Airlines no longer exists. Orient Thai Airlines launched it as Thailand's first low-cost airline, and it began flying domestic routes from Bangkok Don Muang Airport (DMK) on 3 December 2003. The brand was retired in July 2010, when its aircraft and operations were absorbed into the parent airline.

What One-Two-GO was

One-Two-GO was a low-cost subsidiary, or brand, of Orient Thai Airlines, run by the same owners and sharing aircraft and management with the parent.

The two names are still mixed up regularly, including in fleet listings that credit One-Two-GO with Orient Thai's Boeing 747s. Under its own name it flew McDonnell Douglas MD-82, MD-83 and MD-87 aircraft, and a Boeing 757-200.

Where it flew

One-Two-GO flew domestic routes, from Don Muang rather than Suvarnabhumi.

Chiang Rai and Phuket were its flagship destinations. Chiang Mai, Surat Thani, Krabi and Hat Yai were also on the network.

The 2007 Phuket accident

On 16 September 2007, One-Two-GO Flight 269 crashed on approach to Phuket International Airport. The aircraft was a McDonnell Douglas MD-82 registered HS-OMG, landing in a thunderstorm when the crew broke off the approach to climb away and try again. It struck an embankment beside runway 27 during that go-around and caught fire.

Ninety of the 130 people on board were killed and 40 survived. Early reports gave the toll as 89, and 90 is the figure ultimately recorded.

Thailand's Aircraft Accident Investigation Committee (AAIC) investigated, assisted by the United States National Transportation Safety Board (NTSB). Its findings were:

• the crew did not follow standard procedures for a stabilised approach, for call-outs, or for the go-around;
• the take-off/go-around switch was not pressed, so thrust and airspeed did not increase as they should have during the go-around;
• crew coordination was insufficient and the workload was high;
• the weather near the airport changed suddenly;
• crew fatigue, linked to accumulated stress and insufficient rest.

Early speculation blamed windshear, a sudden change in wind speed or direction. The AAIC found it was not a determining factor.

The recommendations covered emergency training and crew rest scheduling. FlightGlobal reported the findings at the time.

The European ban and what followed

The European Commission added One-Two-GO to the European Union (EU) Air Safety List on 8 April 2009, barring it from European airspace. The listing cited the airline's safety management and the standard of Thai regulatory oversight at the time. FlightGlobal covered the listing when it was announced.

After the accident, Thailand's Department of Civil Aviation suspended operations over crew duty hours and training records. Reports put the suspension at 56 days.

The One-Two-GO name was dropped in July 2010 and its flying passed to Orient Thai. Orient Thai stopped flying on 9 October 2018, suspended by Thailand's Civil Aviation Authority over unpaid fuel and airport fees and its debts. Thailand's Central Bankruptcy Court declared Orient Thai bankrupt with effect from 14 September 2021.

Who flies these routes now

Thai AirAsia and Nok Air both launched in 2004, the year after One-Two-GO, and both fly domestic routes from Don Muang today.

There is no operating airline left to contact about an old One-Two-GO booking. The brand went in 2010, and Orient Thai, which absorbed it, stopped flying in 2018.

Frequently asked questions

Is One-Two-GO Airlines still flying?

No. The brand was retired in July 2010 and its aircraft and routes went to its parent, Orient Thai Airlines, which itself stopped flying in 2018 and was declared bankrupt in 2021.

Is One-Two-GO the same airline as Orient Thai?

One-Two-GO was Orient Thai's low-cost brand, owned and run by the same people and flying the same aircraft. It was not the name of Orient Thai's wider operation. The One-Two-GO name went in 2010; Orient Thai carried on flying until 2018.

Are old One-Two-GO tickets or bookings still valid?

No. There is no airline left to honour one. The brand went in 2010 and Orient Thai, which absorbed it, stopped flying in 2018.

What happened to One-Two-GO Flight 269?

It crashed at Phuket International Airport on 16 September 2007 during a go-around in a thunderstorm, and 90 of the 130 people on board were killed. Thailand's accident investigators found that standard procedures for the approach and the go-around were not followed, that the take-off/go-around switch was not pressed, and that crew fatigue and a high workload contributed.

Which Bangkok airport did One-Two-GO use?

Don Muang, not Suvarnabhumi. Thai AirAsia and Nok Air also fly domestic routes from Don Muang today.
