FEDEX is great out of BOS. I havent done it in a couple of years. Take the water shuttle bus out to the dock and let the driver know you want to go to FEDEX. The driver will drop you off after stopping at the dock. Press the buzzer and they will send someone to get you. They will give you a code for the door to ops...put it in your phone So you can go to the bathroom while waiting for your flight.

When arriving...If I remember right there is a way to call for the bus to take you to the terminal in the bus stop shed...I would ask one of the ops guys before going outside.

Get on Mike's good side while you are there....he's a great guy.
