Thai AirAsia has stated it wants to start commercial operations from Suvarnabhumi on September 25th, three days before the airport will open for all commercial operations on the 28th.
The last ten flights on the 24th will land at NBK, so that the airline is ready to start operations from there the next day.
All airlines are supposed to relocate to NBK in the night of 27/28 September. A Thai minister has said he would like domestic operations to start there on the 15th already, to check for any 'bugs'.
Undoubtedly the move from Don Muang to Bangkok will bring total chaos to the aviation scene here! Let's wait and see what happens...
