When Is the best time to book flights for the holidays?

With the holidays just around the corner, it's time to start looking into booking your flights. 

Google has released some of the best times to buy your airline tickets, based on four years of aggregated Google Flights data and other trends. 

Here's the latest insight, according to Google. 

Domestic flights

The average price for U.S. domestic flights is at its lowest 38 days before departure. Historically, prices dipped at their lowest between 21–52 days before takeoff.

International flights

People looking to fly to another country should look at airline prices as early as they can. Average prices are usually at their lowest 101 days before departure. Historically, the low price range is anywhere from 50 days or more before takeoff. This means international airline tickets don't dip before departure but instead rise within 50 days of departure.
