Searching for and comparing flights used to be a massive pain in the neck, even just a few years ago. You’d either have to check each airline’s website individually, or you’d have to go through one of the many online travel agencies (OTAs) that often showed different prices.

Of course, this was the easiest it had ever been…before the internet became what it is today. Back then, your only choices were to call the airlines or go into a travel agent’s office!

Things got a lot better in 2011 when Google Flights launched following Google’s purchase of ITA Software, a travel and reservations software company.

In the few years since, a stream of improvements and innovations has brought the program leaps and bounds ahead, making it the single most useful tool for both deal-seeking travelers and those looking for luxury.

In this guide, we’ll go over the basics of the tool, including some newer features that can help you find the perfect flight.

What Is Google Flights?

Although this tool lets you search for, compare, and purchase flights, it’s not technically an online travel agency like Orbitz or Priceline. Rather, it’s a highly effective metasearch engine that saves you the step of searching each airline and website individually.

You can compare routes, prices, times, airlines, and more to find the cheapest, most convenient, or preferred flight between any airports.

There are a couple different ways to use the tool, including 2 primary functions that have a few components:

  • Regular flight search
  • “Discover Destinations”

Below, we’ll go through each of these tools so you know how to use them.

Hot Tip: Google Flights finds fares and then directs you to the airline’s website or an OTA, and so we like to use a card that earns bonus points on travel purchases, such as the Chase Sapphire Preferred® Card which earns you 2 points for every $1 that you spend with the card on travel or dining purchases. If you’re a business owner, we’d strongly recommend using a rewarding business credit card when making a travel purchase.

Flight Search

While the other features that Google Flights offers are definitely useful, its basic flight search functionality is the heart and soul of this tool. It’s not quite perfect and doesn’t have full access to every airline — specifically, it can’t access prices for Southwest Airlines — but otherwise, it’s the best way there is to search for flights.

Basic Searching

Google has a relatively minimalist search screen, but it offers advanced options as well. To use all of Google Flights’ new search capabilities, you will need to visit the Google Flights homepage and select “Try Now” on the right side of the page to use the new beta version.

Once on the new search page, just enter your origin, destination, and dates. (Note that if you have location services enabled, the city is already filled in for you.)

Google Flights Home
The Google Flights search screen

Because Google is so fast, results will start popping up for a default set of dates as soon as you’ve entered an origin and a destination. If that doesn’t happen automatically, just hit return or enter on your keyboard when you’re ready.

As you enter dates, a calendar pops up showing the lowest available prices for dates that month.

Google Flights Calendar

For example, in the above screenshot, I see that I can save $20 by flying a day later.

After you’ve picked dates, click “Done” and the results will be listed under the search area. The top result, with its price highlighted in green, is typically the least expensive flight. There are also a few other flights included in a “Best Flights” box — according to Google, these itineraries are chosen:

“…to give you the best trade-off between price, duration, number of stops, and sometimes other factors such as amenities and baggage fees.”

This means the prices in that box (other than the low price highlighted in green) may be higher than other options lower down in the results. However, you can filter the results by price, departure, arrival, duration, and more.

Google Best Flights
Results typically show a few “Best Flights” as well as tips if you can save a lot by traveling on a different day.

Above the best flights results, you’ll see four boxes including Dates, Price Graph, Airports, and Tips. Under Dates, you will be shown if cheaper prices are available on other travel dates near yours. The Price Graph will allow you to see a pricing trend going for dates before and after those you have selected. The Airports box will allow you to select other airports near the one selected to compare prices. Finally, the Tips box will bring you to a page that might include an option to book a class higher than selected, a guide to the destination city, and a link ot the Google Tips app.

There are a few filters you can use to narrow your search. Click the links under the date fields to select the number of stops, price, times for both outbound and inbound flights, and airlines.

Google Search Filters

If you click “more” in the filters list, you’ll see a few other options. The first is self-explanatory: use the slider to select a maximum duration of your flight. This is useful if you’re flying far away with connections, but don’t want to spend too long traveling.

For example, a flight to Asia may be cheapest with layovers, but if those are lengthy your travel time could be more than 40 hours. Use this filter to keep the duration lower. If there are no results because you set the duration too low, you can always change it later.

Another option is whether to always show or always hide “separate tickets.” In a few rare cases, it may be cheaper to book 2 one-way tickets rather than a round-trip. By default, these are always shown, but if for any reason you don’t want them, you can just click “hide.”

Hot Tip: Use the filters under the date fields to narrow down and refine the results!

After you enter locations and dates, you’ll find a few more items if you click the “more” link under the search fields. Exactly what shows up depends on the flights you’re looking at — one item allows you to specify where you want to connect if you have a flight with stops.

Avoiding Basic Economy

Google Flights has added notifications when you select basic economy flights. You’ll see a gray “Basic Economy” box on a flight option once selection, with information on what is included and what is not.

Unfortunately, you cannot exclude basic economy entirely from searches – the functionality consumers really want.


Scroll through the results and click on one that interests you. Some itineraries show just 1 flight option, but others may say something like “4 similar flights.” This means that the airline/alliance shown has a few different flights available for a similar price and the same number of stops.

When you click the result, you’re prompted to choose your actual outbound flight (if there are similar flights). If there’s only 1 choice on that result, you’ll be prompted to pick your return flight.

Keep in mind that the price shown on the initial results screen is the lowest possible price for that itinerary. This means that depending on which return flight you pick, it could be more expensive. This isn’t really an issue; just make sure to pay attention to the prices of each return flight.

Google Flights Booking
Once you’ve picked your flights, you’re ready to book!

When you’ve chosen your flights, Google offers a few options for booking — generally, these are the cheapest options it can find.

Usually, the first (and cheapest) option is to book directly with the airline operating the flight, but sometimes Google gives you the option to book through the airline’s partners or whichever online travel agencies offer the best deals.

Click the price button next to your chosen booking method; you’ll be redirected to that website to make your reservation. The travel details are already set, so all you need to do is confirm them, enter your personal information, and pay.

Tracking Prices

Google has a tool that lets you track flight prices. You can set an alert, and Google will send you an email if prices go up or down.

To set an alert, look under the booking sites after you’ve chosen an itinerary, and click the price tracker button (take a look at the screenshot of results above). If you’re logged into Google, the alerts will be sent to your Gmail. Otherwise, enter an email address.

Google Flights Tracking 1
Once you turn on flight tracking, you can check the price history since that date at any time.

You can access any flight price alert you set by clicking on the 3-line menu icon in the upper-left corner of Google Flights and clicking “Tracked Flights.” You can also see a graph with price changes from the day you set the price alert going forward.

Google also has an option to share your chosen itinerary before actually booking it. This is helpful if you’re looking up flights for someone else to book, or if you’re trying to make plans to travel with someone else.

You’ll find the sharing buttons right under the price tracker button. You can either email the itinerary to yourself to save for later or share it with someone else.

To send it to yourself, click the button on the left. Just like with the price tracker, if you’re logged into Google it’s sent to your Gmail; otherwise, enter your email address.

To share with someone else, click the button on the right. A window pops up with options to get a link to copy and paste, enter an email address, or share via social media platforms like Twitter, Facebook, or Google+.

Bottom Line: Google Flights is arguably the most effective way to search for flights, and it has powerful tools to help you find exactly what you’re looking for.

Discover Destinations

We’ve just discussed how to utilize the newest layout of Google Flights which is still in beta testing. If you want to use the popular Discover Destinations function, you’ll need to start from the older version of the Google Flights homepage. For now, this is the default when you visit Google Flights.

When you go to the homepage, before you start entering destinations and dates, you might notice a map and popular destinations below the search boxes.

This is a really interesting tool. Have you ever wanted to plan a trip, but weren’t really sure where to go? This might be the perfect way to find some travel inspiration!

There are 3 main ways you can search: dates, places, and interests.

Discovering Destinations With “Discover Destinations”

google flights discover destinations
Scroll down on the Google Flights homepage to find the Discover Destinations tool.

The Discover Destinations section has a few search options up top, with a bunch of “cards” underneath showing different locations, places, and prices. There’s also a map in the upper-left corner of the section with markers indicating different places you can go.

As you enter search criteria, the cards change to reflect what you’ve entered so far.

The first variable you can use to search is the dates. You can choose an upcoming month and trip length from the available buttons, or you can choose specific dates by either entering them up top in the flight search area (or by clicking the link that reads “Select specific dates” next to the month buttons).

If you want to narrow down the cards a bit, click “Places” to switch the search field. This is meant to be fairly broad — after all, if you knew the exact city you wanted to fly to, you wouldn’t need to use the discovery tool!

google flights discover destinations search

Buttons with continents appear by default, or you can use the search bar to find a region, country, or state. You can’t search by specific city, though (use the search tool for that instead).

For example, you can specify “Europe,” “Northern Europe,” “United Kingdom,” or “Scotland,” but you can’t enter “Edinburgh” or “Glasgow.”

If you have a particular idea of what you want to do on the trip, try the “Interests” field by clicking the button. There’s no text box, but you can pick from a list of options. Choices include adventure travel, beaches, food, honeymoon, shopping, wildlife, and winter sports.

Tweaking the Cards and Booking

If you don’t see something that piques your interest, keep playing around with the options, either selecting specific dates, different places, or different activities. Once you find something that appeals to you, click on that card.

When you open a card, it expands to show more detail — in particular, it shows a few different activities, the top 3 flight options, and the general costs of hotels.

google flights discover destinations cards
Click a card to see more details about a trip.

Click the side of the card with flights to open the standard flight search screen with the dates and airports already entered. If you want, you can adjust your dates or change your departure airport. From here, the process to book, save, share, or track flights is the same as with a normal search.

If you’re ready to book hotels, hit your browser’s “back” button to go back to the destination card, then click the section with hotels. There isn’t exactly a dedicated hotel equivalent of Google Flights — instead, you use regular search or Google Maps. Clicking the card brings you to a search page for hotels.

You can sort by relevance (which is based on Google’s search algorithms), price, or rating, and you can see each hotel’s location on the map. Make sure the dates listed at the top are correct; in my test searches, they often defaulted to different dates.

google flights hotel search
Click on each result to see more information about the hotel, including where to book.

As you click on each hotel result — either in the list or on the map — a window pops up with a few more details and options for booking, including directly with the hotel or through OTAs.

For activities, click each one to learn more — a new window opens with search results. For example, if I click “history” on the card in the above screenshot, the search terms will be “Lima Peru History.” I’ve found this tool to be a little too general, but it can still be a helpful way to find inspiration.

Best Ways to Use “Discover Destinations”

I find the discover tool is useful if I know that I want to go on a trip, I have a general idea of when I can take off, but I don’t know exactly where I want to go. In my experience, results have been more helpful when I’ve kept the search criteria more general — for example, picking a month and duration rather than specific dates.

I also prefer to only pick activities or region; not both. That helps me find places or things to do that I otherwise might not have thought of.

Hot Tip: You can find a lot of travel inspiration in the “Use Points” section of our site!

The “Explore Destinations” Map

Instead of entering search terms, another way to use the Discover Destinations tool is to browse a map. When you first go to the Google Flights home page and scroll to the tool, you’ll notice a map in the upper-left corner of the Discover cards.

google discover destinations home
Click the map to explore destinations.

If you click the map card, a full-window map pops up with dots marking various places you could go. You can enter dates and a departure airport in the upper-left, and when you hover over the dots you’ll see the lowest available price for tickets.

You can also use filters at the top to control number of stops, maximum price, airlines, duration, and interests. As you set these, the prices will change and the number of dots might decrease to match your criteria. For example, if you enter “winter sports” as an interest, most tropical or desert destinations will be eliminated.

Once you pick a destination, a panel appears with specific flight options and hotels. Just like with the cards, click each section to make any necessary adjustments and book.

google flights explore map

If you’re looking for some inspiration, you can also try the “I’m Feeling Lucky” button. Just enter your dates and any other criteria, then press the button. Of the available destinations, Google picks one for you at random. If you don’t like it, you can always go back or click the button again.

Bottom Line: The discovery tools built into Google Flights can help you find your next vacation spot!

New and Special Features

Google’s been improving the Flights tool since it launched in 2011 by making it faster, adding new functionalities, and adding airlines and options. Price tracking is just one of those newer features.

Price Prediction and Fare Expiration

In October 2016, Google announced a new tool that would notify people looking for flights if prices were expected to change soon.

Airline fare rules and planning are incredibly complicated and hard to figure out, so there’s no guarantee that Google’s prediction will be correct. However, in a few test cases I’ve found it to be fairly accurate.

The tool only pops up if you’re looking for a flight that’s expected to change prices soon — you won’t see it otherwise. A red flag appears next to the “Best Flights” box or the specific flight and says when prices are expected to change.

Better hurry up and book!

Click “Learn more” to see more information, including Google’s reasoning behind the prediction. It says when prices usually change, how often that happens, and by how much.

Flight Delay Notification and Prediction

Google Flights will not only now tell you of flights notifications and their reason, during search it will also predict delays to inform your purchase decision.

Overhead Bin Access

Google Flights has added a flight results filter to show which options include access to an overhead bin for a carry-on bag.

Legroom (Google Chrome Extension)

Earlier this year, a private developer launched a free extension for the Google Chrome web browser that adds information about seats to Google Flights search results.

google flights legroom
The Legroom browser extension is only available for Google Chrome

When you search for an economy class ticket, you’ll see the particular flight’s pitch (distance from the back of one seat to the back of the next seat) on the right-hand side of each result. Flights with a smaller pitch are highlighted in red, while flights with a more generous pitch are in green.

If you search for a premium cabin, you’ll see the type of seat on the flight — for example, a recliner, angled-flat, or lie-flat seat.

This is a fantastically helpful tool! As airlines are still working to make their fleets uniform following mergers over the past few years, it’s helpful to know exactly what kind of seat you’re paying for, especially since it can vary based on which plane is being flown on the route.

Bottom Line: New features continue to be brought into the software tool — whether officially through Google or through third parties.

ITA Matrix

Google Flights is built on software that Google acquired when it bought ITA Software in 2011. That software still powers Google Flights, and if you want basically complete control over your search — from routing and fare code to the tiniest detail — you can access this software’s advanced interface.

ITA Matrix can be quite complicated, but the tradeoff is that you can search with much more control. If you’re interested in learning more, check out our complete guide to ITA Matrix.

Final Thoughts

Google Flights is my first stop anytime I’m looking for flights. It includes most airlines, features great prices, and searches various online travel agencies and airline websites to save you the time. Even if I plan to book through an OTA, I always search GF first.

There’s just one catch to be aware of: Google doesn’t have access to pricing for Southwest Airlines flights. Whenever Southwest operates a route, it’ll appear at the bottom of the flight search results, but you’ll have to click it to visit Southwest’s site and see the price for yourself.

What is Google Flights?

Although the tool lets you search for, compare, and purchase flights, it’s not an online travel agency like Orbitz or Priceline. Rather, it’s a highly effective metasearch engine that saves you the step of searching each airline and website individually.

You can compare routes, prices, times, airlines, and more to find the cheapest, most convenient, or preferred flight between any airports.

How does Google Flights work?

The software tool works by searching databases from each airline and online travel agency to find flight schedules, seats, and prices.

Behind the scenes, it works by using a program called ITA Matrix, which was originally developed for travel agents and reservation managers.

Can you book through Google Flights?

Not exactly as the tool itself is just a search engine. That means that unlike a travel agency, it’s not the one selling you the flight.

However, Google includes links with each result to the cheapest available place to book — usually directly with the airline, but sometimes through an online travel agency or one of the airline’s partners.

That said, there are 2 recent exceptions: you can book tickets on Lufthansa or Virgin America directly through Google Flights.

How reliable is Google Flights?

In theory, any service or search engine can make mistakes. However, the tool gets its information directly from the airlines. That means that if there’s a mistake or something incorrect, that’s because the airline did something wrong.

Are Google Flights reservations refundable?

Because you’re not booking directly through Google, you should be sure to check the policy of whichever website you purchase your airfare from, as well as any restrictions with the particular fare you’ve bought.

    What currency is used for overseas flights purchased from US browser location? For example, you want to book a flight from Sydney to Cairns, Australia — do you see prices in US dollars, or Australian dollars?

    Hello, I bought tickets online (Norwegian/Easyjet)

    I called the airlines and was told that I must make the change with my travel agent, that I cannot do it directly with them. In this case, it is Google Flights as my ticket was bought using their service as a travel agency.

    But I can not find any way to contact Google Flights to change my reservation.
    Do you have any suggestion please?


    • Hi Ines – Google Flights does not directly book any fares. This is likely why you can’t find a phone number to call and address your booking.

      Google Flights is a big metasearch engine which means it aggregates tons of information to give you all of the options you’re looking for. When you select your desired flights and are given a price, Google Flights then directs you either to the airline itself, or an OTA (online travel agency) that is advertising said fare.

      Google Flights has made this a pretty seamless process, so it’s likely you were redirected to an OTA and didn’t quite pick up on that. It happens to a lot of people!

      We suggest taking another look at your official confirmation e-mail for your flights, then contacting the OTA which sent you the e-mail.

      Hope this helps! 🙂

    What has happened to ? I am not seeing it as of today June 8. I would use this tool to judge places to go in a region and the best time to go. I hope google did not end that page.

      Hi David

      Google recently integrated a new Google Flights platform. Here’s the link to the old platform

      • Hunter · July 12, 2018 · Reply

        Are you still able to access the old interface. I tried your link and it sent me to the new site.
        I can’t seem to locate the map with prices to every airport in the new interface. Thanks

        • Christine Krzyszton · July 12, 2018 · Reply

          Hunter, the map with prices can be accessed on the new interface by clicking on the menu which is represented by three short horizontal lines in the upper left-hand corner next to “Google Flights” in the blue bar at the top of the page. The three options you should see are: Search Flights, Explore Map, and Tracked Prices. Hope this helps.

    Hello, While I can appreciate the new google flights I believe the older one that used to be accessed through the running man to be more user friendly when searching for other airports and other features. I would love to be able to use that one as well but the option seems to have disappeared. There were other links for awhile but those are gone as well. Can you help? Thanks

  5. Ashamed to confess I have never used Google Flights before. Having read this post, I’ve immediately tried out this tool myself. And here you go—Naples, France will be my first destination chosen with Google Flights. Thanks for a great insight.

  6. Strange error in pricing: I’ve been monitoring a multi-city flight from LAX to Abu Dhabi, via Istanbul on Turkish, one way, then Cairo to LAX, via Istanbul on the return. Google Flights says it’s $6371 on business class, but when I click on the price it then says “from $4971” – it sends me to Turkish airlines with several other options, but the one I wanted on their site is $4971. Not sure why G. Flights is giving me $6371.

  7. I loved the feature of just typing two cities or airport codes in the search bar and get connections between the two cities with schedule. Somehow it doesn’t work since a couple of days….

  8. So here is the thing.

    I used to type in the Google search bar two airport codes or even two cities sometimes and I would get the timetable of the nonstop and other connections. I loved it because I could quickly see what nonstop existed and what airlines would otherwise fly the quickest, although you wouldn’t see anything else. This feature was tremendously useful.

    Since about three weeks it doesn’t work and instead I get the prices directly. But I don’t want that.

    • Christine Krzyszton · August 15, 2018 · Reply

      Thanks for your comment, Paul. I’ve actually had the occasion to need this lately and just used the non-stop filter to give me the flights I wanted to see but unfortunately no actual timetables.

  9. We prefer to have Sri Lankan rupee LKR in your currency list. otherwise, we have to open a separate google currency convert window and needs to check each time to calculate our cost and that is a pain.

    • Hi Saman, please note that we are not Google or Google Flights, so we cannot address this request. We are Upgraded Points, a points & miles based website who publishes information related to points, miles, credit cards, travel, etc.

    I’m trying to book a ticket for my son to return from Portugal. Google flights tells me there’s a flight through Air Europa for $464 and to call the airline to book. When I call the airline, the price with them (and on their website) is >$3,000, not a small difference. I understand that Google Flights is a search tool but in this case, I’m curious where they’re getting the price from that it’s so vastly different.
