FRA CX lounge is quite small especially since other OW members use it
No F section!
BUT
it is directly opposite the security check gate and they have a Premium line for Biz and F pax
Nice belegtes brot open face sandwiches and good announcements
Only 4 computer stations
Inadequate lounge if you have paid for a CX F ticket
and
being Terminal 2 you get off the train and have to take the shuttle or skyrail from Terminal 1
