Air Berlin

Surprised at complete lack of lounge when flying Air Berlin out of Berlin. Because of the need to get transfer passport control and security check at gate you really have no option and then you're in a space too small for the number of people bad wifi inadequate lighting dirty and 1 food vendor as the only amenity. This business class lounge experience was quite surprising. Once I was on-board the experience was great but the departure experience will keep me from connecting through Berlin again.
