Logan Airport in Boston is the most convenient. The Barn in Carlisle is about 30 miles north-west and about 40 minutes (when no traffic) from Logan Airport.
Suggested Limo service, if you don't want to rent a car.
About $90 each way.
They will be waiting for you at the gate.
I use them whenever I fly. Arrange several days ahead.
