Google Flights is constantly evolving, but it remains the one tool I always mention when people ask me how to find better flight prices.

This easy-to-use website can help you find the best possible price on airfare (and even hotels). It’s one of the best weapons in our TPG arsenal for saving money on travel. TPG posts deal alerts, but if you're looking for a particular flight, destination, airline or routing, Google Flights is the way to find personalized deals.

Google Flights now even lets you filter out basic economy fares.

It's where I almost always begin my search for new bookings. I come back to it again and again to book trips, see if prices have dropped and check if I can get a better deal.

The site has rolled out a feature on the search pages that lets you find the "best" or "cheapest" flights, which I'll break down a bit more below. I've also written a complete guide to Google Flights Explore, an incredible feature within Google Flights.

Here’s everything you need to know to use and master Google Flights.

What is Google Flights?

Google Flights is one of our favorite tools for finding flight deals. Not only is it an amazingly powerful flight search engine, but it's also super easy to use. Google shows you nearly all available flights for a search, but doesn’t force you to book with it.

Unlike Expedia, Orbitz, Tripadvisor or Kayak, it’s not an online travel agency. Google is simply showing you what’s available. Once you find the flights you like, you can “click through” to actually book. You can book directly with the airline or via a third-party OTA, but not through Google itself.

Google Flights now shows you 'cheapest' and 'best' flights

When you search Google Flights, a tab just above the results shows either the "best" or "cheapest" flights.

New tabs within Google Flights. GOOGLE FLIGHTS

Google describes the best flights as those that "balance price and convenience, taking into account factors such as duration and number of stops to keep your journey smooth and affordable."

Meanwhile, its cheapest flights category comes with the following caveat: "These additional budget picks help you save but may involve trade-offs, such as flying back to a different airport in the same city you departed from, self-transferring luggage, or booking via a third-party site."

Sometimes, these categories overlap. For example, check out the options for this trip from Taipei, Taiwan, to Seattle. Google lists nonstop flights on airlines like Starlux Airlines, Delta Air Lines and EVA Air as the best flights; when you toggle over to the cheapest flights, you'll see the same flights displayed again. In this case, the best flights are also the cheapest.

However, you will sometimes see vastly different results on different itineraries. Here's an example search from Atlanta to Santiago, Chile. When I start on the best flights, the best option is a direct flight on Delta for more than $1,400 — but once I've clicked over to the cheapest tab, I can find flights as low as $784. I personally wouldn't want to have to fly different carriers with multiple stops, but your opinion may vary.

Anyway, play around with these features and see how much you can save.

Google Flights now lets you screen out basic economy

Google's new filter to screen out basic economy fares. GOOGLE FLIGHTS

As you can see in the screenshot above, you can now filter out basic economy fares. It's a feature that we wanted for years, and Google has delivered. Simply click the fare class tab in your initial search to open a drop-down menu where you can select "Economy (include basic)," "Economy (exclude basic)" or premium-cabin filters.

This saves me a lot of time, since I usually don't book basic economy fares due to all the restrictions.

Here is a side-by-side comparison of a flight search from New York to Los Angeles. If you include basic economy, you'll find flights as cheap as $338 round-trip, but if you exclude those cheapest seats, the price jumps to $377 (still not a bad deal).

Some other great features at Google Flights

Google has also introduced features that suggest when prices are historically lowest and when you should book to get the most savings. Google has always shown whether the price for a suggested flight itinerary is typical, low or high, but now it gives you even more data to consider.

According to Craig Ewer, who works in communications at Google, the tool will “let travelers know when airfares are expected to be lowest for booking their chosen dates and destination."

For example, Google shows me that a flight from New York to San Francisco in October was $93 cheaper than usual and that the typical range is between $245 and $415. In other words, it was a good time to book.

It gets even better: In some situations, Google will suggest alternate dates to help you save a few bucks. The example below shows that a December flight to Miami would have been much cheaper if I had waited until Sept. 13 to book it.

Basics of Google Flights

How to perform a basic flight search

First, you’ll want to navigate to Google Flights.

The toolbar has additional features for trips, including things to do, hotels, vacation rentals and a shortcut to that cool tool I mentioned earlier called "Explore." However, we’ll focus on using the main tool to book flights for now.

All of the fields and drop-down menus on this page are relatively easy to decipher:

Departure (where you want to fly from)
Destination (where you want to fly to)
Date(s) of travel
Round-trip flights, one-way flights or multicity trips
The number of passengers (but you should search for a single ticket, even if you’re traveling in a group)
Ticket class (economy, premium economy, business class or first class)

If you know where you’re going and when you want to be there, all you have to do is plug in that information.

For example, here are all the options I see when I search for flights from New York City’s John F. Kennedy International Airport (JFK) to San Francisco International Airport (SFO). You can search by destination or by airport code.

Note that, as mentioned, Google automatically displays the flights it considers best based on a combination of factors, such as price, route convenience, number of stops and travel time. Of course, these may or may not be the best flights for you.

Regardless, there are plenty of options to choose from.

Once you’ve found the flight you want, you have the option to book directly with the airline. Google will give you several options for the type of ticket you want to purchase, including basic economy, refundable and other fare types.

Clicking the blue button would take me to the American Airlines website, where these flights and prices would be preselected for me. There, I could enter my passenger details and loyalty number, select a seat and pay for the ticket.

Sometimes, the cheapest option is to fly the return trip on a different carrier. However, Google Flights clearly indicates that two tickets must be purchased separately.

For example, in the itinerary shown below, the cheapest option involves mixed tickets with multiple stops. Most people won't want to take that option, as it involves booking through a third-party website (so you won't get the perks you'd get when booking directly with the airline), with tickets on different airlines and multiple flights and layovers. No thanks.

There are many ways to filter your searches. We’ll explore that a bit more below.

Search by specific times of day

Say you want to take a weekend trip. You need both flights to occur outside business hours, but not too late in the evening, as you don’t want to land in the middle of the night.

Thankfully, Google Flights lets you filter by time of day to find flights that best fit your schedule. No matter how inexpensive those off-hours flights may be, a 3:30 a.m. wake-up call or arrival rarely feels worth it.

See how many bags you can bring on board

In the same series of buttons below your Google Flights search, click the “Bags” button to specify how many pieces of luggage you want to bring on board.

This selection may greatly limit your search results — or drive up your price options — so be prepared for some flexibility if necessary.

Nonstop, one-stop or any flight will do?

Similarly, you can filter flights by the number of stops along the way. Sure, you might be the glutton for punishment who longs for a 50-plus-hour flight with multiple layovers. However, if you want to minimize the chance of delays or disruptions, have a family to rush back to or just want a shorter flight, then nonstop is your friend.

Headed overseas? A one-stop flight will usually be the sweet spot between price and comfort.

Search for flights from your preferred airline or alliance

If you don’t fly often, the operating airline may not matter to you as much as the price does.

However, if you’ve begun accumulating miles and status with a specific carrier, you may want to stick with that carrier and program. The exclusive benefits of elite status can be exhilarating, and there’s nothing more exciting than booking your first award flight — especially if you know you got an amazing deal.

With filtered airline search results, Google can help you keep that momentum going. Use the button under the search results to filter out unwanted airlines or select specific airline alliances you want to patronize. Or, you can simply turn off the “Select all airlines” option and manually select your preferred carriers.

Whether booking with cash or points, you may want to stick with one program to maximize mileage earning or status. For example, if I were trying to hit Diamond status on Delta Air Lines, I would search only for Delta flights.

You can also pick airline alliances like Oneworld and SkyTeam to ensure you travel on your preferred airline or its partners. In this case, I would select SkyTeam.

Connecting flights

You can also decide whether to fly nonstop or how many stops you are willing to make, and you can even choose the connecting airport.

Some airports are better for connecting than others, especially for international flights. For example, Helsinki Airport (HEL) is lovely; on the other hand, Paris-Charles de Gaulle Airport (CDG) and Amsterdam Airport Schiphol (AMS) can be challenging even for the most experienced travelers.

If there are many flight options from, say, New York City to Rome, with a choice of connecting airports, you can filter the results to only show the airports you want to connect through.

You can also choose how long you would like your layover to last. You might want to keep it short to reach your destination as quickly as possible. Or you may prefer a long layover to allow for some buffer time in case of delays.

Score the best legroom and other seat amenities

Don’t you hate boarding a flight to find your knees touch the back of the seat in front of you? Fortunately, Google Flights now shows you how much legroom to expect on your next flight before you purchase a seat.

Legroom can differ noticeably from carrier to carrier and aircraft type to aircraft type. From the search results below, you can see that Frontier seats are below the industry average at 28 inches, while JetBlue's are above average at 33 inches.

If you value legroom, JetBlue offers 5 inches more than Frontier. In coach seating terms, that’s a lot.

In addition to legroom, Google Flights will also indicate whether to expect Wi-Fi access on your flight (and whether it is free or at a cost), whether the plane has in-seat charging options, and whether the flight offers entertainment like live TV or options to stream to your personal device.

Your devices may run out of juice on a flight longer than five hours, so you may want to choose the product that best suits your needs rather than selecting entirely based on price or carrier.

Know your emissions

Sustainability is an increasingly hot topic when it comes to travel. Thankfully, Google Flights will calculate your flight's approximate carbon emissions based on the route, aircraft type and seating classes.

Below are the search results for a flight from Los Angeles International Airport (LAX) to Tokyo’s Narita International Airport (NRT). United Airlines operates a fuel-efficient Boeing 787 on this route, which would produce lower-than-average carbon dioxide emissions of 734 kilograms. However, the Singapore Airlines flight uses a less fuel-efficient (and larger) Boeing 777 aircraft that produces a higher-than-average 1,163 kilograms of carbon dioxide.

You can even filter your search results only to show lower-emissions flight options.

How to search by the cheapest dates

Let’s say I want to get from JFK to LAX in September, but I’m not tied to any specific dates. Google Flights can help me find the best possible prices for that trip.

On the search page, when I click the calendar icon, I can see the lowest price for that day. Prices listed in green represent the lowest price available across all current dates, while the days highlighted in blue show which dates I’ve selected.

Another way to view the cheapest dates is to click the date grid option. This will again show the cheapest dates in green, and you can easily line up different outbound and inbound options to see if the cheapest dates work for you.

You’ll often find that the cheapest flight isn’t necessarily the best or most convenient route. Google will show you the lowest prices, but it prioritizes better routes before them.

In this example, Google Flights prioritizes slightly higher fares as “best flights” because they include a full-size carry-on bag.

How to set a price alert for yourself

After all that diligent work, give yourself a pat on the back. You’ve likely found the best option for yourself.

Some people are ready to book immediately, but most of us might need a day or two to solidify our plans with our fellow travelers or with work. Never fear: Google will help you track your flight and even tell you when the price goes up or down.

Immediately above your search results, there's a little toggle that reads “Track prices” (boxed in green in the screenshot above).

Click on that — and log in to your Google account if necessary — and Google Flights will send price alerts directly to your inbox.

If you have booked a refundable or changeable fare, you may want to switch this on even after you’ve booked. You will be alerted if the price goes up or down, so you can feel comfortable knowing you are getting the best deal. The screenshot below shows part of the list of flights I’m currently tracking.

How to search multiple airports at once

Sometimes, you’re willing to land or depart a bit farther away in order to find a better flight deal. Google Flights can help reward that flexibility. In fact, you can enter as many as five departure or arrival airports on Google Flights.

Let’s say you live in New York City, where you have three major airports to choose from. You want to fly to Southern California, which is easily accessible from multiple airports as well.

There are two ways to run this search:

Type in your city name and let Google offer suggestions: This works for many major metro areas. As soon as I type in New York, I see several of the major airports: Newark Liberty International Airport (EWR), LaGuardia Airport (LGA) and JFK. Sometimes, you’ll even see New York Stewart International Airport (SWF) near Newburgh — about 60 miles north of Manhattan — as an option.
Manually type in your airport codes or names: Some cities won’t show you all the logical potential airports. For Southern California, you will have to manually enter the names or codes of each airport in the area for some searches. Don’t forget San Diego International Airport (SAN) as a potential option.

Voila: The cheapest option for March 18-25 is a nonstop, round-trip flight from EWR to LAX for $258 in United basic economy.

How to check for carry-on bag policies

I don’t care what anyone says: Low-cost carriers can be fantastic for finding great deals.

However, if you’re a heavy packer, you’ll need to plan ahead. Many airlines cut costs by charging extra for bags. You’re used to this with major airlines, but some ultra-low-cost airlines will even charge you for carry-ons larger than a backpack or a purse.

It can be difficult to track which airlines charge what, but Google Flights can help with that, too.

Basic economy flights will appear in the search results page, with the small “no luggage” icon next to the price.

When I click through to the final booking page, Google will remind me that I’m booking a basic economy flight; it’ll show my current price and its limitations while also displaying economy and first-class booking options next to it.

How to find the best getaway deal

This function is similar to the previous tip but focuses on another aspect of your search. Start by clicking the “Explore” button on the toolbar.

If you know you want to get away on specific dates — let’s say the second week of October — but don’t have a specific destination in mind, use Google’s open-ended search functionality to find good flight deals within your window of availability.

In the example below, I picked a long weekend in October and set New York City as my departure airport. Instead of specifying a destination, I just left it open-ended. You can give Google a hint by typing “Europe” or “Caribbean” to narrow your search results to a specific region.

If I zoom in closer on the map, the system recalibrates and shows me more destinations and price points within the updated map view.

If I zoom out for a world view, I’ll see the best-priced destinations of note around the globe.

I can also force the algorithm to show me price points for a specific region.

For example, the world map above doesn’t show me many deals for Australia, South America or Africa. However, if I zoom in on Australia, I see more than half a dozen options on the continent and more than a dozen in “surrounding” areas.

Google Flights is an incredibly powerful tool that the TPG team uses daily to price airfare. It can help you quickly find the best flights for your desired trip, but it can also track prices and let you know if you are getting a good deal. It can help you plan trips as well as find hotels and activities.

It’s one of my favorite tools to find deals and new places to visit. Add it to your own travel toolbox, and I promise it will become one of your favorites, too.
