I'm flying from JFK to Berlin via Frankfurt, LH business class both ways.


To Berlin, I have a 4 hour layover in FRA in the very early hours of the morning. Other threads suggest that my time would be best spent in the Welcome lounge, is that correct?

On the return trip, I also have a 4 hour layover in FRA, from 1pm until 5pm. What should I do with myself? Which lounge? Any other fun to be had at the airport?
