I need to book a paid ticket from Phuket to Bangkok to connect with a CX award flight out. Air Asia is cheap and has a 2h10m layover. However, a similar layover at PVG was recently almost disastrous, as there was no transit between CX and AA. I was funneled directly to the customs queue and had to find the AA desk in the terminal with two minutes to spare before missing the 60-minute cut-off.

Does anyone know if Suvarnabhumi is the same, or whether I'll be able to stay airside and check in at a transit desk? I'll have no bags. I've searched for 20 minutes but found nothing. Thanks!
