Last year we changed it up a bit and will do it again this year. We are in Boston and leave in the afternoon on Friday, spend the night in Charlotte, then get an early flight to MBJ.

Takes longer, obviously, but allows us to get in early and avoid the bad lines (the non-stop from Boston gets in at 2:30, I think). Also we save a lot of money on airfare AND don't have to deal with the potential for a blizzard in Boston completely messing up our return home. We spent 3 hours in customs coming home in 2015. No more.
