Summer has officially arrived, and it’s vacation season once again. It’s one of the most popular times of the year to travel, which can make hopping on a flight a much more expensive endeavor. The good news is that you don’t have to pay an arm and a leg for a flight if you know where to look. Even during the peak of summer, it’s still possible to find
affordable flights
, and Google has tons of information to help you make an informed decision.
Google Flights has released a robust travel report
after aggregating four years of airfare data and trends to provide US travelers with an overarching guide on finding the
cheapest flights
and the best times to book them. I have reviewed this report thoroughly and highlighted the most important takeaways below to help you find a flight in your budget and let you relax while traveling instead of stressing about money.

What days are the cheapest to fly?
If you’re planning to book a flight, you’re likely trying to find the most budget-friendly option. According to Google Flights, the cheapest flights are available when flying on Monday, Tuesday and Wednesday, with
Tuesday being the cheapest day
, according to the historical flight data.
Flying early- to midweek can save travelers 13% to 20% on airfare compared to flying on Friday, Saturday or Sunday, with
Sunday the most expensive day
to fly.
Do layovers on flights save you money?
It may come as no surprise that flights with layovers are cheaper than nonstop flights but you may not realize just how significant those savings can be. The Google Flight data shows that
travelers can save 25% by booking a flight with a layover
instead of a nonstop flight.
Which day of the week is the cheapest for booking flights?
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.
Google Flights does state that
Tuesdays are typically the cheapest day of the week to book
, according to the data, but Tuesday bookings are only 1.3% cheaper than the most expensive day, Sunday.
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. 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” for international travel from the US.
When is the best time to book a flight in every season?
Here’s what Google says about the best times to book holiday flights and vacation trips to certain popular destinations.
