I flew to Krabi domestically on a PG flight on Thursday. The board showed MANY airlines that it was codeshare for, but if there was anyone connecting I have no idea when they boarded because I never saw anything special except the normal waiting area connected to the terminal which I doubt they would let international connections wait in.
The whole thing is still highly confusing and they really shouldn't have even thrown it into the mix in my opinion.
