== History ==
The airline started operations on 3 December 2003.<ref name="FI"/>

Following the crash of Flight 269 in Phuket, Thailand on 16 September 2007, One-Two-Go was banned from flying in European Union nations due to safety concerns.<ref>{{cite news |title=EU Bans Thai, Ukraine, Kazakhstan, Benin Airlines From EU |newspaper=The Wall Street Journal |url=https://online.wsj.com/article/BT-CO-20090408-704139.html |access-date=2017-03-14 |archive-date=2009-04-12 |archive-url=https://web.archive.org/web/20090412065822/http://online.wsj.com/article/BT-CO-20090408-704139.html |url-status=live }}</ref>

On 8 April 2009, the [[European Commission]] added One-Two-Go Airlines to its [[blacklist]] of airline operators banned from entering European [[airspace]].<ref>{{cite web |date=2009-04-08 |title=EUROPA - Press Releases - Commission updates the list of airlines banned from European airspace |url=http://europa.eu/rapid/pressReleasesAction.do?reference=IP/09/560&format=HTML&aged=0&language=EN&guiLanguage=en |access-date=2012-05-16 |website=Europa.eu |archive-date=2009-04-13 |archive-url=https://web.archive.org/web/20090413152245/http://europa.eu/rapid/pressReleasesAction.do?reference=IP/09/560&format=HTML&aged=0&language=EN&guiLanguage=en |url-status=live }}</ref>

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.<ref name="expose2">{{cite news|year=2007|title=Cut Price Safety|work=Australian Channel 9|format=mp4|url=http://investigateudom.com/files/OTG_expose.mp4|url-status=dead|access-date=July 14, 2011|archive-url=https://web.archive.org/web/20120327162159/http://investigateudom.com/files/OTG_expose.mp4|archive-date=2012-03-27}}</ref> 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.<ref name="expose2" />

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.<ref name="timesonline2">{{Cite news|date=2008-07-20|title=Families Blame Lax Safety for Budget Airline Crash|work=[[The Sunday Times]]|url=http://www.timesonline.co.uk/tol/news/world/asia/article4364087.ece|access-date=2011-07-23|archive-date=2008-09-06|archive-url=https://web.archive.org/web/20080906200058/http://timesonline.co.uk/tol/news/world/asia/article4364087.ece|url-status=dead}}</ref>

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.<ref name="NTSB Report2">{{cite journal|year=2009|title=One-Two-Go Airlines Flight OG269, HS-OMG September 16, 2007, Phuket, Thailand|url=http://investigateudom.com/files/NTSB/427510.pdf|journal=NTSB/Dca07Ra063|publisher=National Transportation Safety Board|access-date=July 14, 2011|archive-date=March 27, 2012|archive-url=https://web.archive.org/web/20120327162132/http://investigateudom.com/files/NTSB/427510.pdf|url-status=live}}</ref>{{rp|29}}<ref name="Lawsuit2">{{cite journal|year=2008|title=Deceased v.

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. Coroner, S.P.G. Fisher. Coroner Fisher relied on a British aviation investigator, the NTSB, and Thai reports, and victim and family statements to make his conclusions.<ref name="Coroner Report22">{{cite web|author=Fisher|first=S.P.G.|year=2011|title=HM Coroner's Summary into the 8 Inquests of an Air Accident that Occurred on the One-Two-GO Airlines|url=http://www.investigateudom.com/files/InquestStatement.pdf|access-date=July 14, 2011|archive-date=July 13, 2011|archive-url=https://web.archive.org/web/20110713051746/http://www.investigateudom.com/files/InquestStatement.pdf|url-status=live}}</ref> He cited the "flagrant disregard for passenger safety" by the airline and said, "the primary failure so far as I am concerned relates to the corporate culture which prevailed both One-Two-Go Airlines and Orient Thai Airlines prior to and following the air crash." Fisher twice contacted the airline to send a representative to the hearing. The airline replied that they would not take part in the proceedings.<ref name="Coroner Report22" />
