There is an interesting development with huge legal and financial ramifications for Air Asia - Indonesia in the loss of the Air Asia A320.
Air Asia - Indonesia did not have legal flight approval for the flight that has been lost. They were not authorised to fly SUB - SIN that day.
The reasons are not 100% clear at this stage but Air Asia - Indonesia are no longer flying the SUB - SIN route.
Having some knowledge of the Indonesian system I suspect there is a flurry of paperwork behind the scene with many documents and approvals being backdated by the DGCA. (All being done with God's approval)
If there had been Americans, Japanese or Australians on board there would have been a lawyers picnic in the making.
Ps. Air Asia Indonesia is 49% owned by Air Asia and 51% by the former
Indonesian carrier Air Wagon International. The name Abd Wahid (Gus Dur) may be familiar to some old timers.
