The jetways in the Geneva airport (only those in the roundabout) operate symmetrically opposite to the normal jetways, for this reason they have the staircase and the service exit on the opposite side. There are currently no GSX level 2 models working in this mode. I have to do some tests to verify that SODE allows the resolution of this kinematics, so I see if can create special jetways for LSGG in the next update.
