I just landed at KSLC, and requested a gate. GSX said it was too small, and that no services would be available. I tried about 10 more between 4 terminals, and same thing. If finally just pulled up to the closest one B9 (which I tried to select), and selected "deboarding", and it worked fine.
I'm using default KSLC, and the PMDG NGX.
Why would the request deny me, but when I got to the gate and parked, it worked?
Thanks,
John
