I LOVE MHT and avoid Logan like the plague!!! I went to pick up family a few weeks ago late in the afternoon and noticed a line to check in, but it was for Delta. I did not notice one for Southwest. There are still guards patrolling and security is still searching bags, people, etc. No one without a ticket is allowed near the gates. If you are flying Southwest and are on the first flight out, then I would plan on 2 hours prior to the flight to arrive. Even if you have a paper ticket, you still need to check in at the counter downstairs (unless this has recently changed). This will allow enough time to check in downstairs, check any luggage, then head upstairs through security, then wait in line to get your boarding cards. Plan on bringing things for the kids to do both at the airport and on the plane, such as travel games, coloring books, etc. When I went last September and took that flight, the line was very long. This is a popular flight to be on, since it is their first one of the day to MCO.
