Unfortunately, we inherit the placement/rotation of the Jetway and Bridge of the default scenery, good or bad, because it's the only way to be sure we could keep up with future updates in the MSFS default database.
Because it we tried to add tweaks that might solve this, like changing parking positions, jetways positions and rotation, the next MSFS Navdata update would break all our modifications.
By keeping it the same, even if airports have changing parking spots or moved jetways, it would be enough for us to recompile a new version taken from the updated original files, it's an automatic process for us.
About the model, we assigned both the smooth and the corrugated version to the US, with some major airport forced to be corrugated, otherwise the choice is random, by airport.
It might be an interesting community project, collecting a list of airports, which kind of jetways it has, eventually which color (we do have multi color variations, we just haven't made a proper assignment to ICAOs ), which logos, and we might integrate it in our database, and regenerate the whole world again. With such a list, regenerating the whole world takes like 5 minutes.
