I find going directly to an airlines site works the best for me, I keep an eye on it for a few days and quite often the price drops if the plane is not filling, you are also leaving on a Friday and the prices are always higher for weekend flights, try looking at the flights available on the 27th, that leave late in the evening.I would also suggest going to the airport and getting on a standby list, but being Christmas, the busiest flying season, it could take hours and hours.Have a great Holiday
