I swore I would never do this, but this year I'm actually flying on the day before Thanksgiving. We'll be leaving on a 3pm flight from Washington Dulles to Florida (not Disney, unfortunately). I've already made arrangements for someone to drop off/pick us up so we don't need to deal with the parking issue. I'm now I'm just unsure of how early we should get there. I expect lines to be long and chaotic. How early should we arrive for a 3pm flight? I was thinking about noon? Once we're through security, we could sit and eat lunch in the terminal, waiting for our flight. Thoughts? Suggestions?
