Yeah for sure as I have ground vehicle set to very limited number and with the exception of the tow truck there is no other ground services in the other parking stalls. I don't know if you have noticed but with the new update or SU14B, when I land and as I open the GSX Pro tab, I can select the parking spot and then the airline but then the tab quickly disappears and a new tab opens which say revoke this position, remove AI, etc.! This quick closing/opening of the tab may be the issue. But I am not sure. Hope you encounter the same yourself and perhaps you can tell what's causing this.
In general though, per our prior conversations, it would be awesome if you can add a tab or two in the GSX setting so we can set a default airline for our airplane and a default catering. If an airport has those liveries/services available then the code should be written such that those will automatically be selected for your airplane. If not, then the user should choose which company's services they prefer. This would make this much more realistic and I know you strive for that.
Thank you.
