I am a great fan of the Frankfurt FCT lounge. Make sure you plan some time to spend there, enjoy the wonderful facilities (you can use the FCT as an arrivals lounge as long as you are connecting on another LH
flight and you hold a F boarding pass from your connecting flight) and your limo ride to the aircraft for your next flight.
I can assure you this is an experience you will really enjoy. As to the onboard service, amenity kits, PJs and food, I much prefer SQ
and the Singapore Girls and boys rather than the LH
matrons still LH
is not bad at all. Just worth it for the FCT alone!
