Some of us were around, what maybe 2 decades ago, when there was a 500 baht exit fee collected at the airport. The process was quite straightforward. The problem is more about what happens to the money afterwards.
Flew Qatar this week BKK-LHR business. The first flight delayed an hour because of some paperwork we were told, but arrived to pick up second leg on time. BKK business lounge good. Doha business lounge very busy. Transit security also at 6am. I would say that the food offerings and lounge comparable with Emirates at BKK. A380 both legs. Next flight booking also Qatar but only 777.
After using wm clothes are damp but not wringing wet. Can be hung up on drying rack. Happy to begin discussion on different types of clothes pegs and electric iron brands.
Many of the shops inside and alongside TukCom will have for sale new but older model budget Samsung phones for sale. You might still need to push that budget up towards 3k though.
There's a place on Soi Buakhao towards the Pattaya Tai end and on the corner before the Tuesday/Friday market. It must be the real thing because there are a number of bean bags outside to roll about on.
