Love paying full price for airline tickets? We didn’t think so. But sometimes you don’t have a choice. Maybe there are no award seats available, or a trip comes up last minute. So how do you find the cheapest airfare without searching every airline individually?

There are a lot of 3rd-party websites, like Orbitz, Expedia, etc., to choose from. But I’ve found Google Flights is one of the best ways to find cheap flights. And it’s got some pretty cool features, too! Here’s a rundown of the various ways in which you can use this handy tool.

It’s easy to find cheap flights with Google Flights!

4 tricks to finding cheap flights using Google Flights

Google Flights is a powerful airfare search engine, with it you can do so much more than just basic city to city searches. It allows you to search for cheap fares over entire regions and a wide range of dates at the same time.

You can also set price alerts and view airfare prices from your origin to cities across the entire map, all at once. If you’d like to learn how to set up a Google Flight price alert, check out this step-by-step guide.

Trick #1: Do a map search

Suppose you don’t have a destination in mind but want to see airfares from your city. Type in your city name and date range, and a map will come up with sample fares to various cities.

You can move around the map and zoom in or out to see prices to different cities.

And if your dates are flexible you have the option of viewing the best prices over a range of dates. Just click on the dates box, then select “Flexible dates” and you’ll be able to view prices for a weekend, one week, or two week trip for a specific month or an entire six-month period.

I love using this feature to search for cheap flights to an entire continent because my travel dates are usually flexible. And once you get to Europe or Asia it’s easy to find cheap flights to your final destination.

To see flights to a specific city, just click on that city.

After that, click “View flights” and you’ll be brought to the standard Google Flights search. Here you can filter the results by the number of stops, specific airlines or alliances, departure or arrival time, and connecting airports.

A really handy feature is that you can even add the number of carry-on bags you plan to carry to your search.  So if the airline charges extra for a carry-on, it will already be factored into the price.  Given that most airlines have Basic Economy fares, which usually don’t include the price of a carry-on, this will give you a better idea of which ticket is actually the cheapest.

You can choose the departure and return flights you want and then you’ll be given the option to buy the flight from a number of different sites.

One thing to be aware of when you’re booking your flight is that some credit cards award bonus miles or points for airfare, but that there are some restrictions when it comes to earning these bonuses.

For example, with The Platinum Card® from American Express, you can earn 5X Amex Membership Rewards points on airfare if it’s purchased directly with the airline or with American Express Travel (earn 5x points on up to $500,000 on these purchases per calendar year). So purchases on other 3rd-party sites, like Priceline or Orbitz, won’t earn bonus points.

Most of the best travel credit cards that earn bonus points on airfare or travel purchases, like the Chase Sapphire Preferred® Card and Chase Sapphire Reserve®, don’t have such specifics restrictions.  But be sure to double-check so you don’t miss out on your rewards.

Trick #2: Confirm you’re getting a deal 

Google’s basic flight search has all of the standard features you’d expect, with a few extra bells and whistles that can help you find the best deals.

For example, when you search for flights there is a box at the bottom of the page that will tell you how the current prices you’re seeing compare to what that specific flight normally costs. In this example, for a flight to Amsterdam, the price is what Google would expect – not a bad deal or an exceptional deal.

Google looks at airfare prices for the previous 12 months to your destination (and dates) to determine what they expect the price to be.

Trick #3: Search for separate tickets

You can also potentially save money by purchasing separate tickets on different airlines to your final destination. The potential drawback of this is that if you need to cancel or make changes you’ll have to pay the change or cancellation fees twice. But Google Flights allows you to search for or hide separate ticket itineraries.

Trick #4: Compare lots of prices at once

Google Flights has several different ways for you to quickly compare prices on different dates, times, and from different airports.

Once you enter a city pair in the search you can easily scroll through the calendar to see the cheapest prices. Just click on the arrows on the left and right to see different months.

You can also compare prices using a grid of dates.  Just click on “Date grid” (see example below) where you enter your search information.

Then a price grid, like the one below, will pop up.

From there you can view a price graph.

And you can view prices from alternate departure or arrival airports.

As always, the key to finding the best deals is to be as flexible as possible. But even if you have a rigid schedule, Google Flights can quickly and easily help you locate the best prices for flights that work for you.

If you get stuck, you can get help through the Google Flight support page.

Pros of using Google Flights

Google Flights is just a search tool. You can’t book directly on the site. But the site searches very quickly, so even though you have to book elsewhere you’ll still save time.

Cons of using Google Flights

One downside is that you can’t search for Southwest flights, because Southwest prefers you to search through their website directly. This is a big deal for anyone with a Southwest Companion Pass. So don’t forget to try your search on the Southwest website, too.

If you want to be sure that you’re comparing the prices for every flight to your destination, a good trick to look up your destination’s airport on Wikipedia.

For example, let’s say I want to find a flight to Columbus. I can pull up the Wikipedia page for its airport, John Glenn Columbus International Airport, and scroll down to see a list of airlines that serve it.

Once you know what airlines fly to your destination you can double-check the prices for any that might not show up on Google Flights. Although, as far as I know, Southwest is the only major airline that is specifically blocked on Google Flights. If you know of any others, let me know in the comments and I’ll add them to the post.

Bottom line

Google Flights is a great tool for finding the cheapest airfares. It’s fast and you can customize your search by using filters to narrow down your results.

But Southwest flights are not included in Google Flights searches. So if you were planning on taking advantage of your Southwest Companion Pass or using Southwest to connect to a larger airport where you can find cheaper international flights, then you’ll need to be sure to search Southwest’s site directly.
