I've flown ten long haul F segments with TG in the past year. I'm still waiting to run into a service debacle that has me running here to vent.
I've had TG crews ranging from excellent to average. I have never had a below average crew on TG. I've had far greater service issues on my SQ and JL flights.
Yes, I have had one or two longer than average check-in experiences. I've also have been escorted without a buggy to some of the "closer" gates. Even with those minor issues I can't think of a better ground experience in Asia...
