According to the website Skyscanner.com, this week is the best time all year to buy flights for the holidays.

They looked at data from last year to see when people are most likely to book, and that affects the price.

Tickets for around Christmas are 19 percent cheaper than normal right now. So a ticket that’s usually $300 might be more like $240.

Tickets for Thanksgiving are about 6 percent cheaper. Also, tickets for New Year’s Eve are 15 percent less expensive than normal, if people actually fly somewhere for that.

Don’t panic if you’re not ready to book your trip yet though, because you can still get a decent price for the next few weeks. Tickets will just gradually get more expensive.

Like, if you book by the end of the month, a flight for around Christmas should still be 13 percent cheaper than normal.

Apparently two weeks before any holiday is a decent time to buy tickets. They should be about 5 percent cheaper than average at that point.
