None of them are GSX jetways.
- Be sure you run the Live Update and have the latest version of JFK.
- Be sure you allow the AFCAD to be updated by the updater, when asked.
- If you have an old GSX customization file you made for JFK, remove it from the %APPDATA%\Virtuali\GSX folder, otherwise your customization will take precedence over the scenery one, and if yours was made before we added SODE jetways to JFK, no jetways will show.
