The train option
Coming back by train is also possible but the train only has 2nd class a/c seats which are 551 Baht and would involve a 10 hour plus journey on Sunday slated to arrive at Don Muang on paper in good time to connect with either a Thai Lion flight at 19:50 (575 Baht) or the last flight on a Sunday to Hatyai at 20:00 (Air Asia: 1340 Baht). So the cheapest option is as follows:
Tues. April 12, HDY - BKK, Air Asia, 17:40 -19:05; BKK - UBL, Thai Rail, 21:00 - 07:30 (Wed)
Sun. April 16, UBL - BKK, Thai Rail, 07:30 - 17:38, BKK - HDY, Lion Air, 19:50 - 21:10
This works out around 3000 Baht depending on your choice of bunk position on the train up, with a 1st class berth adding another 500 Baht and the Air Asia flight instead of Lion Air on Sunday adding another 750 Baht.
Food for thought.
