I am flying into Terminal B at Boston/Logan on US Airways and have only 64 minutes to make a connection to Icelandair in Terminal E.

Is there a way of making the connection but not having to go through security again? I see that there are airport terminal bus routes, but is there a way just to walk and stay inside? It looks like the gate that I am arriving into (B19) is on the other side of a parking garage from the part of the terminal closer to Terminal E.

At Terminal E, is there a first class/Preferred/etc. security lane? Or any quick way to make it through security? I am first class on US Airways but not on the connecting airline (although I'd gladly pay any kind of fee to avoid the long security line).

Thanks!
