Google Flights has released a comprehensive travel report, aggregating four years of airfare data and trends to provide US travelers with an indispensable guide to finding the cheapest flights and the best times to book them. **Best Days to Fly**
One of the most crucial factors in determining the affordability of flights is the day of the week. According to Google Flights, the cheapest flights are available when flying on Monday, Tuesday, and Wednesday. Tuesday is the cheapest day to fly, with a savings of 13% to 20% compared to flying on Friday, Saturday, or Sunday.

**Layovers on Flights: A Cost-Saving Option?**
While it may seem counterintuitive, flights with layovers are often cheaper than nonstop flights. According to Google Flights, travelers can save 25% by booking a flight with a layover instead of a nonstop flight. This is likely due to the increased competition among airlines to fill seats on flights with layovers. **Best Day to Book Flights**
There is no significant benefit to buying tickets on a specific day of the week. However, Tuesdays are typically the cheapest day to book, according to the data. This is because many airlines tend to launch sales on Mondays, which can lead to discounted fares for the rest of the week.

“There’s not much benefit to buying your tickets on a certain day of the week,” says Google Flights. “Tuesdays are typically the cheapest day to book, but Tuesday bookings are only 1.3% cheaper than the most expensive day, Sunday.”

**Booking Flights Far in Advance**
To wait or not to wait? According to Google, it’s generally better to book your travel far in advance, especially if you need to fly on a specific day or time. For domestic flights, prices tend to be lowest between 21 and 52 days before departure, with 38 days out being the cheapest day to book on average. For international flights, prices are generally lowest between 50 and 101 days before departure, but it’s best practice to book as early as possible. Google states, “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.

**Best Times to Book Flights by Season**
Google provides valuable insights into the best times to book flights for popular holidays and destinations. * Spring break: The cheapest domestic flights in March and April are available between 33 to 59 days in advance, with 44 days before departure being the cheapest time to book on average. * Summer break: The cheapest domestic flights in July and August are usually available 13 to 43 days in advance, with 21 days before departure being the cheapest day on average to book. * Thanksgiving: The cheapest domestic flights over the Thanksgiving holiday are usually available between 26 to 59 days in advance, with 45 days out being the cheapest — meaning it’s best to book Thanksgiving flights in early October. * Christmas: The cheapest domestic flights over the winter holidays are usually available between 36 to 72 days in advance, with 58 days out being the cheapest. It’s best to book Christmas or holiday travel in the latter half of October. **Best Destinations for Holiday Travel**
