For many people, paying for distressingly expensive airline tickets is just part of life when it comes to traveling for the holidays. And, while you might think you’ll get the best deal by checking fluctuating prices obsessively from today until the day before Thanksgiving, you’re probably better off booking your flights right now.

“Once you get within three or four months, the chance of something cheap popping up for Christmas or New Year’s is not very likely,” Scott Keyes, the founder of Scott’s Cheap Flights, told Travel + Leisure. “Certainly don’t wait until the last week or two because prices are going to be way higher.”

This is partially because airlines devise algorithms based on last year’s ticket sales and trends, and they know many travelers will fork over some serious cash rather than decide not to go home for the holidays—and there are always plenty of people who wait until the last minute to book their flights. In fact, so you know for next year, the absolute best time to book holiday travel is actually during the summer.

Scott Mayerowitz, the executive editorial director of The Points Guy, admits that it is possible to save a little money if you’re extremely diligent about following flight prices leading up to the holidays, but he thinks your mental health is worth much more than the pittance you might (or might not) save. “The heartache and headache of constantly searching for the best airfare can drive you insane,” he told Travel + Leisure. “Your time and sanity [are] worth something.”

If you’re not willing to throw in the towel just yet, you could always track the prices for a little while, and give yourself a hard deadline for booking your flights in a few weeks. Mayerowitz says buying your seats at least six weeks in advance—or earlier—is a good rule of thumb for holiday travel. That still leaves you several weeks to periodically scroll through flight listings and get a feel for what seems like a reasonable price.
