I am not judging life in BKK nor am I using a hotel representative.
I am a simple TG C passenger who expects the advertised benefits and it would not surprise me if at my next arrival I would be miracoulosly granted fast track immigration. I might have been unlucky and others like
dsquared37 did not encounter this problem.
Should it however not work, I guarantee that TG will not get away with it this time. Most of you might not know that Thais LOVE to sue people and companies for more nonsensical stuff - and I fully agree that fast track is not a matter of death or life

.
It's the inconsistency that makes Thailand a place that can become unexpectedly dangerous in some cases. To all of you making a joke of my post I wish that you never encounter something more frightening in Thailand.
I also have spare fast track cards, the new golden ones (the previous ones are not accepted anymore

) and of course I could use the central premium lane with them. These cards I have from so called reputable airlines
