It is not Air Asia or Trigana etc. that should be penalised for apparently operating a flight without a permit. How did Surabaya Airport accept the flight plan and how did the aircraft receive permission for take off from Surabaya tower? Surabaya seems a dodgy place to operate from, nearly caused a CX A330 serious accident by uplifting contaminated fuel for a flight to Hong Kong not so long ago, which was only saved by the skill of the flight crew. No wonder Indonesian air operation audit is one of the lowest in the world with many Indonesian operators banned from flying in EU airspace. I understand that this had nothing to do with the loss of the aircraft but perhaps it wouldn't have happened if they refused to clear the flight that day?
