BKK immigration fast lane
[QUOTE=Dreams; 1223923]I also travel Royal Silk usually, but never found a "fast immigration" lane on arrival. Did I miss it?
Otherwise, yes, on departing, the royal silk counter gets you through in 2 minutes.[/QUOTE]Go the right end of the immigration booths line and there are 3-4 fast lane, one crew / diplomats and "special" (meaning families, wheelchairs etc)
Keep your (royal silk) boarding pass at hands to prove the allowed access, unless you have been given the special card on board (but they do not give it anymore, I think, cost saving). Usually no more than 3-4 people in line per booth.
It is a bit hidden and not clearly visibile. Suggest you walk through the fenced path on the right of the access from terminal to immigration (just where there are some duty free stalls)
