Ahead of the busy holiday travel season, Google is detailing the best time to book your next flight to get the best possible price.

With surging fuel prices have also come much higher plane ticket costs and, with that, everyone’s looking for a deal. In a blog post this week, Google Flights details the best times to book your next flight.

For domestic US flights, the best time is apparently 39 days prior to departure, but the lowest price can fall anywhere between 57 days prior and 22 days prior to the actual flight date. International flights should be booked much further out, with 89 days being the magic number there.

Thanksgiving and Christmas flights bend the rules a bit. Thanksgiving flights are actually cheapest 34 days prior to departure, but Christmas flights need to be booked much earlier at around 56 days.
