I always thought Thai Airways (TG) would have no problem to check thru baggage with Bangkok Airways (PG) for all inbound and outbound flights since they are both Thailand based airlines....BUT I AM WRONG!!!!!

I was just replied by TG that I can't check thru my baggage from HKG/BKK by TG, then BKK/USM (Koh Samui) by PG, since they have no agreement of baggage check thru.

What a BIG disappointment as even Cathay Pacific has no problem for baggage check thru with PG from HKG/BKK/USM.

What I find the most ridiculous is that the other way from USM/BKK by PG, then BKK/HKG by TG, you are able to check thru your baggage!!!
