Transfer between Terminals E and B at BOS?
 

I hope this is the right place to ask this question, if not please accept my apologies.

Is there a way of going between Terminals B and E at Boston while staying airside, i.e. without leaving and then re entering security?

Many thanks in advance for any insights you may have!

No. I'm afraid not.

Terminal B is a separate building, not connected to any of the other terminals, except by bus on the street afaik. Because of the airport layout, with one-way roads that make a loop, I think the bus goes from Terminal E out of the airport to the blue line T (subway) station, and then returns to enter the airport roads again, stopping at Terminal A and then continuing on to Terminal B (which actually has two sides, each separate from the other).

Easier and usually faster to hike through the central parking garage.

'Hike' being the operative word !

(Slight side note...the AA and US sides of Terminal B are now connected: http://www.massport.com/news-room/ne...ctor-april-30/)

Are there any airside interterminal connections at BOS anymore? I don't think there are now that United has consolidated into one place and doesn't need to operate the shuttle.

I just picked someone up from terminal B on Tuesday and if such a connection is in place, it was not obvious/visible. Is it underground?

Both sides are connected. United has moved into the space between the old terminals. They built a number of gates. From Massport's site:

This is not accurate. All of the terminals at BOS are connected by internal walkways, but they are all landside.

Also, during most times, the bus that connects the terminals (Bus 11) does not stop at the subway, so it would go from E to A to B. During off-peak times, Bus 55 operates, which does stop at the subway station.

Finally, as noted above, the two sides of Terminal B are now connected, both landside and airside.

As I alluded to above, you can walk among any of the terminals, and to the Hilton, via the central parking structure and connected Habitrail tubes but that is not much help to the OP who wanted to go E --> B airside.

Habitrail tubes about describes them ( but hamsters/gerbils probably get better treatment in general :-). And better have a lot of stamina, a lot of time, and very little luggage.

From the diagram above, I must have driven right past the new pedestrian connector at Terminal B, and not noticed.

It's not really visible from the roadway as you go around the horn at the top of B.

I suppose you could fly out on US and back on WN (or vice versa), connecting in another city where the two share the same terminal airside area. :D

Any international flight* on any airline that uses Terminal B will return you to Terminal E because that's where the customs and immigration folks hang out. Got a couple of days for the transfer?
