This is quite funny.
LX F passengers can use the Thai F lounge in BKK, BUT
TG F passengers cannot use the LX F lounge in Zurich?
Seems a tad unbalanced, no?
I'm surprised TG allows the LX passengers to use their BKK F lounge if the favour is not reciprocated for their own F passengers in Zurich!
That said, TG F catering ex-ZRH is MUCH better than the catering ex-BKK, which is also ironic.
