I did the walk from A to E just a couple of weeks ago. It was quite easy even with my luggage with me on a cart. I wanted to try for an earlier connecting flight, couldn’t get confirmation on the app, so kept my suitcase with me to ensure that it was on the same flight.

The immigration hall at BOS is huge, especially compared to my home airport of MSP. I’ve gone through there twice in the past year and found it really fast both times.
