We usually fly out of Portland. I find the savings HUGE for the extra hour and a half of driving!
One tip.....don't take the Maine turnpike, take the 295 instead. This saves at least 20 min! and the toll!
We are flying in March and the tickets came to 1100 cnd for four of us out of Portland. Last March we flew Southwest out of NH and I paid 600cnd for four of us! This is another two hours of driving past Portland.....
IF you are going this Nov, I would book sooner than later. Just check out Kayak.com.....it checks a whole bunch of sites for the lowest fares.
Happy Planning! Sandi
