These are two separate issues:
If jetways don't work for AI, it might be caused one of these:
- Your AIs don't have their exits specified in their aircraft.cfg
OR
- It's a LOD optimization effect. Since we optimize for performances using LOD, jetways have animations only when seen from a close distance. This usually means you'll see a jetway moving only on AI close to your viewpoint.
If, instead, jetways don't work on your airplane, this might be caused by one of these:
- Your own airplane don't have the exits specified in its aircraft.cfg
OR
- You are not parked correctly in the middle of the parking spot
In BOTH cases, jetways won't work if you haven't the "Advanced Animations" option enabled in the FSX Graphic Settings
