I flew through Pittsburgh a few days ago and I had some questions.
1. How are the peoplemovers that connect the main terminal to concourses A through D? Is it a tram or moving sidewalk?
2. When US Airways Express used concourse E, did they also operate the A concourse as express flights or were they all mainline?
3. What cities did US Airways Express serve that they no longer serve now?
Thanks in advance.
