While the answer is probably yes, I've never connected from a domestic to international flight out of the bigger tourist airports in Thailand. I'm on two itineraries, the first CNX-BKK, the second BKK-PNH. Both on PG. I know that the bags can be checked straight through and I'll get both BPs in Chiang Mai. My question is, will I be able to be processed at immigration in CNX? With 2 hours between flights I'm not concerned, however things would obviously be easier if this could be taken care of in CNX. TIA.
