boston has 7 different secure areas. if you're arriving and departing on delta on a connection, you will not need to reclear security. otherwise, you're probably going to be changing terminals -- i believe all other transatlantic flights depart from terminal E, which is international and southwest.

if the new procedures are limited to terminal A as stated in the article, you would only see them if you're on a delta transatlantic, and not connecting in on delta, continental, or alaska.
