Unfortunately, this is not GSX L2+SODE, where we could control precisely where each jetway goes and we have the "Preferred Jetway" setting.
Until SODE will eventually arrive on MSFS, we must use the default system, which is a bit primitive. Basically, jetway dock where they can, depending on your position, they dock on the last door on the back and, in some cases, they even dock on the *service* door, with their head twisted.
We tried to raise the issue with Asobo, but it didn't get much traction.
