So I have a 10 hour layover at BKK flying in and out on TG first class. Will they bring me to the lounge or to immigration first of all, when I'm greeted at the plane? Also, what is the best use of my time? Would I be able to stop by the lounge, grab some thing to eat, then go out of the airport to explore, and come back and wait in the lounge before my departing flight? Do you think they would let me leave my carry on luggage in the lounge while I leave?
