I departed BOS on Sunday night June 1st, terminal E was a mad-house. Seems a big part of the trouble was crowd management at gate E8A, just opposite the security checkpoint discharge. This is a bus gate for departures on flights that don't get a passenger loading bridge gate, I saw it being used for flights on Norwegian, KLM, and Azores.
Giant mass of people crowding the small doorway and nearly blocking the security discharge and people trying to from gate <7 area to gate >9 area.
