I'm flying out on B6 (JetBlue) tmw with a BP showing gate C5. I thought this was strange as I don't see a gate 5 in terminal C but at the Massport site I did find a gate way down at the far end of terminal E labelled E3/C5. Does the same physical gate have two designations? I am hoping that I can clear security in C, where I have to check a bag, and walk (a bit far) over there, but then am I just in Terminal E?

I am guessing that since there are not a lot of morning international departures from E this is some attempt to balance gate loads? C does get pretty busy in the morning. Thanks for any insights or confirmation.
