One-Two-GO Airlines Co. Ltd () was a low-cost airline based in Don Mueang, Bangkok, Thailand. Its main base was Don Mueang International Airport, Bangkok. It was owned and managed by Orient Thai Airlines and CEO Udom Tantiprasongchai and his wife Nina Tantiprasongchai. The One-Two-GO brand was retired in July 2010, after the crash of flight OG 269 in 2007 was blamed substantially on misconduct by the airline, with the aircraft re-branded under Orient Thai Airlines. On October 9, 2018, Orient Thai Airlines ceased all operations. History The airline started operations on 3 December 2003. Crash of Flight 269 Following the crash of OG 269 in Phuket, Thailand on September 16, 2007, One-Two-GO was banned from flying in European Union nations due to safety concerns. On April 8, 2009, the European Commission added One-Two-GO Airlines to its blacklist of airline operators banned from entering European airspace. Corruption within One-Two-GO Airlines and the Thai Department of Civil Aviation was a factor for the crash investigators of Flight 269. Australia's Channel 9 broadcast a program in November 2007 which detailed accusations of maintenance fraud and specifically by CEO Udom Tantiprasongchai, coercion and bribery of pilots to fly excessive hours. The program contained an interview with lead Thai investigator Director-General Vuttichai Singhamany as he reviewed the daily flight rosters for One-Two-GO given to him by reporter Ferguson, documenting the Captain and First Officer's schedules showing that both pilots had flown beyond the legal limit for the week and for the month of the crash. Director-General Vuttichai said he would demand an explanation for the fraud from One-Two-GO. In late February 2008, the victim's families, concerned about the impartiality and transparency of the crash investigation, created a website and on-line petition called InvestigateUdom.com calling for a proper investigation into the root causes of the crash. The lead Thai Department of Civil Aviation investigator reported that documents he had received from One-Two-GO were fiction. The National Transportation Safety Board (which were also investigating the accident) report included the true work rosters, obtained by the family of a victim. The United States National Transportation Safety Board (NTSB) report documented possible check ride fraud among four other One-Two-GO pilots in the months following the crash. Three years after the crash, the British government began its inquest process into the deaths of the eight British citizens killed. The inquest, held 22–23 March 2011, was presided over by H.M.
