My husband and I flew out of Logan in Feb. on a Sturday on an 8am Delta flight. Our daught-in-law, who works for Delta out of Green in RI told us to get there 3 hours before our flight. We needed that time. We only sat at the gate for 15 min. before boarding. The security lines were hundreds of yards long. We are going to CA to visit our daughter this week and have opted to leave on the Friday rather than Saturday because of the lines we encountered. The security is very throurough and will take some time. I would get there early if I were you and just grab a coffee and relax before your flight. The flights were so much cheaper out of Logan and that is why we are leaving from there. In May I will be flying out of Green, but their security lines are also very long. So much so that they are now opening them an hour earlier than before.
Have a great trip and don't stress about the lines, just relax and go with the flow.
