Just for the sake of curiosity I checked various days, and when you get really close to the day of the flight, airfares are really cheap. The cheapest flight for next Tuesday is ~150. Same flight day after tomorrow is ~$100. Not sure how much the fact that next Tuesday's/30th proximity to Jan1 influences that price. I'll probably just book the ticket today or tomorrow, would suck to get close to the departure date not find a seat, for the sake of 50 bucks.
