do you have the flight numbers of the sealed route flights from Bangkok to Phuket?
This expat may try to fly from Phnom Penh to Phuket via BKK without clearing Thai immigration at BKK.
I dont think its possible..
But with so many changes ???
I believe Bangkok Airways flies several of the sealed flights to Phuket...as does Thai Smile.
Whatever the ticket cannot be two separate tickets meaning codeshare with Bangkok Airways or Thai Smile through to Phuket on one ticket from Phnom Penh is required.
