Sitting in the BKK TG lounge I see out the window two out of many of the TG buses marked "First/Business Class". Anyone ever ride one of these buses to/from the planes? It's the first I've ever seen of them and always am put on a regular bus with all the economy passengers when I fly in C. So maybe it's something new or maybe they're only used infrequently. The window tinting is too dark to see inside from where I am. I'm pleased to see that TG is at least trying to make the C/F passengers feel more comfortable when then need to be bused to the aircraft. Wonder if *G Y passengers can take that bus as well when boarding the aircraft.
