According to Hopper, an app that decides the best times to fly has released the best times to got those Holiday Flights:
When to book for Thanksgiving
Last year the best Thanksgiving deals came in late September. While you should start scanning flights now, Hopper says you may be able to wait a little longer and book Thanksgiving flights before the week of Halloween. At that point, prices are anticipated to spike.
You can also save money by booking flights for certain days during Thanksgiving. The biggest savings is to leave on Thursday, November 22 and return on Wednesday, November 28. You can also travel on Thanksgiving to save money or leave on Monday, November 19.
When to book for Christmas
Make your Christmas flights a priority, according to Hopper. In fact, travelers should book tickets before buying for Thanksgiving as mid-October should have the best deals. Both trips should be secured before “The Great Pumpkin” makes an appearance.
As with Thanksgiving travel, when you fly makes a difference in price. The best deals are had if you depart on Tuesday, December 18 and return on Thursday, January 4. Since many have to be back to work by the New Year, you could return on Thursday, December 27 and still get a decent fare.
