We leave next saturday (19th) and we'll have to see how things are then but we are usually in Logan 2 hours before. Granted that things have changed in the last day, but when we flew back in April it was a breeze to get through Logan. MCO was another story! We were in line for well over an hour - and that was without a terror threat so I can only imagine what it will be like there now. Make sure you leave enough time on your flight back.
Personally, I will be VERY happy to see The National Guard at the airport! We flew shortly after 9/11 when they had armed patrols in the airport and I thanked everyone I saw.
I am getting very anxious about this upcoming trip. I hate to fly as it is and was already nervous about the tunnel problems, and now the plane issues....
Hope you have a great vacation!
