How to Use Google Flights Data to Get the Cheapest Flights Possible

If you’re planning on doing some holiday traveling this year (or have already started to do so), you’ve likely already sunk quite the pretty penny into airfare and accommodations. But if you haven’t done so yet or you habitually wait until the last minute to do so, you can use a series of tools you already have to snag some of the cheapest plane tickets possible. Google Flights has tons of information you can use to figure out when and where to travel to get the most bang for your buck, and it’s easy to use.

Previously, Google Flights released its key insights on 2024 travel data and trends after aggregating four years of airfare data and trends to provide US travelers with an overarching guide on how to get the cheapest flights possible and what the best times of year are to fly. Now, we’re helping you parse that information with tips on what we’ve learned from Google’s research.
