Just found this on the
www.frankfurt-airport.de website:
Sky Club Lounge täglich 08.00 - 21.00 Passagiere mit Einladungskarten der folgenden Gesellschaften: Aer Lingus, Ukraine, International Airlines, KLM Royal Dutch Airlines, LTU International Airways, Northwest Airlines, Royal Brunei Airlines, Belavia, Lufthansa, Lithuanian, Buzz, Regency Premier Lounges Ltd., Lufthansa Air Plus, Malev Hungarian Airlines, LOT Polish Airlines, US Airways, Priority Pass Ltd.
Does this mean LH SENs or FTLs can use this lounge in T2 no matter which airline they are on (LH does not fly from T2) ?
