Has anyone had luck stopping by a Global Entry interview location and just popping in for an interview? I just attempted to today at BOS, and even though there was a no-show the guy said no walk-ins. I then asked him if they had any cancellations and he said I'd have to go through the "live calendar." I've since gone back to my account and can't find a live calendar anywhere. The only way to get to a calendar is to click on "reschedule my appointment" and I don't want to lose my appointment for early November. Any ideas how to get in sooner as I have a trip aboard Nov. 11th and currently I'm scheduled for Nov. 7th.
