- GSX/Sode jetways can be used ONLY from the GSX menu ( either with "operate jetways" or by choosing Boarding/Deboarding )
- Regular SODE jetways can be used either from GSX menu or the SODE menu.
This means, it would be best if you just used GSX, regardless of the kind of SODE jetway an airport uses, so you don't have to remember which one is which.
And, using non-GSX SODE jetways from GSX has the additional advantage that GSX will send the GSX airplane configuration ( doors ) to SODE, which usually is more precise and more dedicated to a specific airplane compared to the default SODE airplane model database, which is more generic.
