I do feel that AUS needs to get it's crap together. I pushed back, after a courtesy call to ground from the north gates only to eventually find myself nose with another jet on a single lane taxiway. Terminal to my right, fence to the left so I had no options.
AUS literally couldn't care less.
Luckily, the other jet was able to get wing walkers so he could make a 180 degree turn as I got a great up-close POV with the sharklets and the APU exhaust.
After a bunch of these things, we talk to our own operations to make sure the taxi lanes are clear and there's no conflicting traffic before we give an advisory call to ground about pushing, but it might be time for ramp control.
My thoughts were that the 737 shouldn't have pushed if Virgin was in sight, AUS needs to put it's big boy pants on and the editorial comments from all parties were unprofessional. Fight it out through ASAPs because radio swordplay doesn't move the dot on the chart and doesn't resolve issues.
