Not busy but station isn't open so be sure to purchase your ticket online. Bus was about half full Noth times I went at that hour.
Not busy, but the station doesn't open until 445am, so have your ticket. I've only taken the 445am and there's room.
That is not my route so i xant say for sure but i have driven ot in the past. I dont believe it is too busy as it is a Logan run for early flights. I would call the 1-800 number for Concord Couch and ask them.
