We always travel from the Halifax airport instead of Maine and here are my tips to make things cheaper.
Fly Tuesday, Wednesday or Thursday.
Plan to book flights about 1-3 months out.
Check multiple times per day for prices.
Know what itineraries you are interested in and write them down.
Check the airline websites as well as retailers such as Expedia.
Make sure you are comparing prices in all US dollars or all Canadian dollars. Decide in advance what price you are willing to accept and book the flights as soon as the price reaches that amount.
They say prices go down Tuesdays at midnight and rise so they are most expensive during weekends but I don't think this is always true.
If you're travelling from December through May also check the charter airlines such as Sunwing and Canjet.
If Moncton is acceptable for you, try to source that airport as well.
I'm looking for February myself and have already broken my own rule. We're planning to travel on Saturday, argh.
Good luck! And be sure to post when you get a good deal.
