Terminal D can be reached by the “Sky Link” monorail, operating free of charge every 3 minutes from terminal A and B/C. the journey takes 2-3 minutes. In terminal D one should follow the sign (Magen David) and opposite restaurant LAXX, turn twice to the left.
The second synagogue is outside the transit area in terminal B, main hall of departures level. One should take the stairs opposite the post office in the direction of the federal police offices (watch the Magen David sign). The synagogue is in room number 201.3409.
