As far as MHT goes and commuting in I am not sure. I work in BIL and not on the flight side of things....I'm in dispatch and get an interesting view of what is going on, that is a little different than a pilot's point of view. I can say right now the schedule that the BOS pilots is not the greatest. The flights are the out and backs but the aircraft overnight in the outstations. I have seen pilot schedule's take them from an early morning crew call all the way to 15 hours of duty with almost 8 hours of flight time....almost, but not quite 8. Like I said before...if one thing goes wrong the system falls apart and you get stuck overnighting somewhere you didn't think you'd be.
I will talk with a captain who is out there and find out the answers to your questions. Give me until tomorrow and I'll have it for you.
