I've got a 9:10 am flight to Heathrow on AA coming up. I'm coming down from the Hanover, NH area, however. Usually, I either use one of the parking services, or I take the bus, but the length of the trip (almost a month) makes the former expensive, and the early hour rules out the latter.

Several hotels down there offer cheap parking if I stay a night, so that's my primary plan, but for around the same amount of money, the two of us can fly down from Lebanon, NH on Cape Air.

But the earliest flight arrives at 7:10am, 2 hours before my flight (I know AA likes earlier arrival for international flights, but realistically, every time I do this flight I spent hours hanging around the departure lounge). Anyone done the Cape Air into BOS and transferred to another airline? As long as it runs smoothly, this shouldn't be an issue (Cape Air is Terminal B, American is Terminal C), but was wondering if anyone else has done this.
