I flew them last July on BOS-LEB. I enjoyed them; staff is very personal and in spite of pouring rain, my flight was on time. You can check a bag for free. There's no OLCI or kiosks; you have to get your BP from a TA. They fly 9 seat Cessnas which provide an awesome view (no cockpit door) but of course are bumpier than most other flights. They use 1 gate at Logan in the JetBlue area of the C concourse, so you will need to transfer over to E.
