There’s no place like home for the holidays — but only if you book your flight soon

If you’re hoping to get a good deal on flights for Thanksgiving and Christmas, it turns out the clock is already seriously ticking.

Travel + Leisure says you should book your T-Day travel no later than Oct. 14, according to its data from the travel site Hopper. 

After that? Well, travel prices seem to sour faster than a mayonnaise salad left on grandma’s table, going up 5% to 10% EVERY DAY.

As for Christmas, you have a little bit longer, with the best prices up for grabs between mid-October and early November. After that, the spike can be as much as 32% leading up to the day Santa takes flight.

Good boys and girls, however, can save $200 a ticket if they’re able to be flexible, the site advises.
