The airport closures at Phuket and Krabi also are prima facie evidence that Thailand is not in compliance with their aviation security obligations under Annex 17. That protesters were able to overpower security forces and take to the runways at Phuket shows that neither the DCA nor the Thai security forces are able or willing to live up to their obligations.
This is reason enough for suspending international air service to and from Thailand immediately.
Who's to say that the same can't or won't happen at BKK, CNX, or UTP? Given that TG, AoT, and AeroThai are releasing their staff to join forces with those that smashed up the terminals in the south, it would be irresponsible to allow air service to continue.
