Today at IAD: Arrived from LHR on UA923. I was one of the first off the plane, and there was a decent line even on the citizen side. The non-citizen side line was huge.
I went up to the GE kiosk, and (I timed it), was finished in 40 seconds. I even beat the deadheading pilot who exited the plane before me, rushed down the stairs, and was first at the crew line.
I noticed there are now four GE kiosks -- I think when I went through a few months ago there were two.
