Boston does a pretty impressive job of fitting a large airport into a relatively small space.

It’s certainly a recurring complaint I have throughout my airport history, but BOS’s biggest flaw is that most terminals don’t connect airside (post-security), so once you’re there, you’re stuck with a limited number of gates to visit.
