According to Kayak's data, you'll get the cheapest flights — both domestic and international — if you're willing to fly on Christmas eve or Christmas day.
The priciest flights depart on the 22 of December and return on the 29 and 30.

You'll want to avoid flying out on the 22 and returning right before New Year's, though.
Since people generally dislike flying on or close to the holidays, the days surrounding Christmas are the most popular — and, as a result, the most expensive. The farther your flights are away from Christmas eve and day, the pricier they get.

Ticket prices spike about a month out, Kayak says, so it's important to be ahead of the curve. The main takeaway from holiday travel is evergreen: the earlier you book flights, the happier your wallet will be.
