Is there a best day of the week to book flights?

While there are certainly cheaper days to fly, there aren’t really cheaper days to book. “There’s not much benefit to buying your tickets on a certain day of the week,” according to the Google report.

Is it cheaper to book flights far in advance?

To wait or not to wait? According to Google, it’s better to book your travel far in advance, especially if you need to fly on a specific day or time. However, there are some patterns you can analyze to decide whether it’s better to wait for lower prices or book now based on specific scenarios, destinations and dates of travel. 

For domestic flights, the prices are generally at their lowest between 21 and 52 days before your trip — with 38 days before departure being the cheapest day to book on average. 

For international flights, the prices are generally lowest between 50 and 101 days before your trip, but it’s generally best practice to book as early as you can. According to Google, “average prices don’t meaningfully drop anytime before departure, but they usually do start to rise within 50 days of the flight itself” when it comes to international travel from the US.
