[QUOTE=blueDC]I don't know how long the train takes but the flight is barely an hour and since there are so many discount airlines in Thailand, the trip from BKK-CNX will cost about $15 each way. [QUOTE]
I've scoured the web and fares from BKK-CNX are around US$100 roundtrip. Haven't seen any fares close to $30 rt. Am I missing something?
