The scheduled 3pm departure Airnorth flight from Townsville to Darwin last Sunday did not leave until 1 am the next day with weary passengers due to some unexplained problem with the plane down the Gold Coast. Now it has been announced in Darwin that the US parent company, Bristow Group , is facing collapse and may file for bankruptcy . A few weeks ago , midst much fanfare, it was announced in Townsville that the airline would extend the Darwin-Townsville route to the Gold Coast. Bristow bought into Airnorth in 2015, providing services to northern parts of WA , NT , Queensland and Timor Leste .
