The Best Websites to Find the Cheap Flights +
5 Useful Flight Search Tips
Before diving into actionable tips and resources for finding cheap flights, it’s important to understand the why behind them. I often get asked, “Why did you recommend this X website over a booking site like Expedia or Travelocity? I’ve never even heard of X.”
Ok, so how many of you have comparison shopped for the best airfare on websites like Expedia, Orbitz, and Travelocity?
I’m willing to go out on a limb and say many of us have done these exact comparison searches for countless trips.
In fact, large travel brands like Expedia, Inc. often own many smaller booking sites for airfare, hotels, car rentals, cruises, and more.
So, when you think you’ve comparison shopped for the cheapest airfare on sites like Expedia, Orbitz, or Travelocity, you may have actually just seen the same results over and over. Even slight price differences in these comparison searches often prioritize the cheapest booking results to include booking sites all owned by the same company.
You’re probably asking yourself, “Then, where should I search for cheap flights?”
To be clear, it’s not that Expedia, Travelocity, Orbitz, and other popular OTAs (online travel agencies) don’t ever have the cheapest flights. But, it’s important to understand the process and why it’s in your best interest to search on websites whose function is not a booking site, but rather a website where airfare prices are pulled from numerous airlines and travel websites regardless of the parent company.
These types of websites are called aggregators because they do just that. They aggregate or bring together all the information about the fare prices for your selected route.
Best Websites to Find Cheap Flights
Using Google Flights to search for cheap flights is simple and straightforward. Enter in your search details and results from many airlines will show. The calendar lets you scroll to check for cheaper dates.
Google Flights will also show money-saving tips if you change your day or airports. There are filters for price, the number of stops, time day, airlines and their alliances, and even the ability to select preferred cities for possible connections. If you’d like to track fares, turn on the “track prices” button to get email alerts for your route.
You can also expand the map view and drag the red marker to different departure and arrival cities to compare fares. However, Google Flights also has a “hidden” explore feature that is perfect for flexible travelers.
This “secret” explore feature shows the cheapest flights to several places in that region, along with bar graphs to that show the range of prices over a few months. (For more on this “let the deal come to you” approach, keep reading below.)
If you find a flight on Google Flights, select that flight and you’ll be redirected to the booking site. Flights cannot be booked directly on Google Flights.
Momondo is a powerful search tool with a lot of possibilities. It’s a comprehensive aggregator that pulls in airfares from over 1000+ airlines, online booking sites, travel agencies, search engines and other travel discount sites.
In fact, studies across a wide range of travel booking sites have shown Momondo to find the cheapest airfare 95% of the time.
At its most basic level, Momondo can search for the cheapest flights on your selected dates, but also shows a bar graph above the results letting you know the least expensive days to fly. With the prices, Momondo shows the seat class, additional fares, and a happiness (or lack thereof) rating.
Advanced search features include selecting connecting cities and limiting searches to specific airlines and alliances. Once your results have displayed, on the right side above the bar graph, you can click on flight insights for your chosen route. Momondo will show historic pricing data, including the days, times, and airlines which have known to be the cheapest.
Momondo also shows numerous budget airlines in their searches. For example, a search for short Southeast Asian flights will show budget carriers like Air Asia, Jetstar, and FlyScoot.
Momondo frequently creates itineraries with different departing and arrival airlines, saving you the time it would take to search each leg individually in order to identify the best price.
With the Trip Finder feature, you can click on a theme like “beaches” or “cities”, set the continent, month, and budget, and Momondo will return with trip ideas and the best times to visit based on price and weather. Even better, in your flight search set your destination to “anywhere” and let Momondo show you destinations.
Momondo is not a booking site so, once you find the flight you’d like, you’ll be redirected to the appropriate booking site.
Some travelers report feeling unsure about unfamiliar booking sites so be sure to read the terms and conditions and, ultimately, book on a site with which you feel comfortable. Momondo is recommended by trusted sources like Scott’s Cheap Flights, Frommer’s, and the New York Times, among others.
To learn more, read why you need to know Momondo for cheap airfare.
Another comprehensive aggregator, Skyscanner doesn’t rely on third parties, but searches over 1000+ airlines, booking sites, and travel agencies for the best airfare.
After entering your search terms, you’ll have the option to see a calendar view or a chart. Both aim to show you the most affordable dates to fly your selected route. Once you choose your dates, Skyscanner will show your results. The results can be filtered by factors like date, time, airline, and alliance.
As with Google Flights and Momondo, you can’t book your flights on Skyscanner. You’ll be redirected to the appropriate website. If you’re booking an economy fare, watch out for basic economy fares versus regular economy, as sometimes it’s not obvious which you’re booking until you’re offered 2 price options while being redirected from Skyscanner.
Skyscanner also has an explore map feature. You can see which cities are affordable to fly to from your home airport. There are also monthly deals which search for the best airfare prices to “everywhere” from your departure city.
Best Resources for Mistake Fares & Deals
A mistake or error fare is exactly as it sounds. Human errors happen and a zero is missed or a decimal point is in the wrong place. If you know where to look and take advantage right away, you could end up with an unbeatable airfare!
Scott’s Cheap Flights
Scott’s Cheap Flights is an email service sending out multiple alerts each day about error fares and deals. You can subscribe for free or pay $39 for a year of premium service.

Cheap Airfare Honorable Mentions
Called a “consolidator” in travel-speak, CheapOair is a website which purchases blocks of tickets from airlines directly for the cheapest rates and then resells them to customers slightly above their cost.
FareDealAlert & Airfarewatchdog
Kiwi operates a bit differently by piecing together the cheapest itinerary with unconnected tickets on a variety of airlines. You can search a range of dates and destinations for the cheapest airfare.
The risk comes if you miss your connection or a flight is delayed because the individual airlines have no responsibility in helping you out because of a problem on another airline. Bags may also have to be rechecked depending on your routing. Kiwi does offer some assurances, though, should you miss a flight or have a flight change or delay. They’ll either reschedule you on the next, most convenient flight or refund the price of your unused tickets. Either way, Kiwi is best for flexible travelers looking for the best price.
AirWander is a flight search tool that calculates the cheapest stopover cities to add to your trip itinerary. A stopover is different from a layover or a connection in that it lasts for at least 24 hours. Adding stopovers to your itinerary adds destinations to your overall trip. And, who doesn’t love visiting more cities and countries when you travel?!
Award travelers are familiar with the concept of stopovers because many airline loyalty programs allow free stopovers on tickets booked with airline miles and points. However, adding stopovers hasn’t always been cost-effective or convenient to figure out when searching on traditional flight search engines. That’s where AirWander comes in. It’s the only flight search website that makes it beyond easy to calculate and add stopovers to your flight itinerary.
Simply enter your departure airport, your destination, and your travel dates. AirWander will suggest cities for stopovers and show the +/- price differences associated with each stop.
5 Useful Flight Search Tips
No matter where you want to fly or which website you ultimately decide to search for cheap flights, it’s not all about which search engine you use. If you’re wondering how everyone else always seems to find a better deal than you, it could be they’re using 1 or all of the tips below.
1. Hide Your Browser.
Websites and browsers store information about the sites you have visited. This could cause prices to go up the next time you return to your search. One way to get around this is to use an incognito window or a private browsing feature while searching for airfare.
If you use Google Chrome, click on the 3 dots in the upper righthand corner to open a new incognito window. Chrome and Safari users can also press “control + shift + N for a new incognito window.
Internet Explorer and Firefox users can use the keyboard shortcut “control + shift + P” and a new private browser window will open.
Keep in mind, you should open up new incognito/private windows every time you search. Yet, even with this, websites will begin to figure out who you are. If you see airfare prices have gone up from the last search in an incognito/private window, switch to a different device.
2. Let the Deals Find You.
Truly savvy travelers who routinely “find” the best deals oftentimes don’t actually do much searching. Quite the opposite, they let the deals come to them.
First, look for mistake/error fares and/or downright cheap deals on websites like Secret Flying and The Flight Deal. Sign up for emails from Scott’s Cheap Flights. When you see an incredibly cheap fare, book it and then figure out why you should go there.
In my travel hacking Facebook Group, a member did just this. He and his wife were looking to take a trip. When they found an unbeatable fare from their home airport to Iceland, they booked. It was only after this when they began researching things to do and all the must-see spots in Iceland.
Bottom line is, being flexible with your destination and taking advantage of deals as they come up can return big rewards.
3. Don’t miss out on a timely mistake fare or deal.
Knowing where to look for deals is only half the battle. You need to make sure you don’t miss out because many mistake/error fares typically are gone in 24 hours or less. With so many notifications, emails, and social media messages vying for our attention, it’s easy for an amazing deal to miss your radar.
Follow Secret Flying and The Flight Deal on social media and sign up for their email lists. If you’re on Twitter, create a list with just a few flight deal accounts so you don’t miss deal tweets.
On Facebook, I’ve liked these pages and set it up so Facebook shows me their posts first in my newsfeed. Like the Facebook page and click the “Following” button for the drop-down menu with options about notifications.
Scott’s Cheap Flights has a premium email service which will even text some of the best deals directly to your phone. This is how I booked an $81 round trip ticket from Philadelphia to Las Vegas or a $320 round-trip flight from New York to Malaysia!
Once you set up a system to catch these notifications, you’ll be better positioned to see mistake fares and deals as soon as they are made public.
4. Do your research.
In order to know if the price you’re seeing is a deal or not, take a few minutes to research what a typical airfare to your destination costs. Eliminating the obvious bargain-basement error fare, how will you otherwise know you should take advantage of a deal or price?
The easiest way to figure this out is to use Google Flights. Enter from your departing and the destination to which you’d like to fly. Click on the field to enter a departure date, but let the calendar open. Scroll through the months and Google Flights will show the departure price for each date. You’re sure to see a price range you can now use as a guideline to make buying decisions later on.
5. Use Wikipedia to find budget airlines.
Wikipedia is a great tool for award travelers trying to figure out which airlines fly which routes. With this information, it’s easier to see which miles or points are needed to book an award flight.
However, Wikipedia is also a great tool to find routes operated by budget airlines, especially when many of these airlines don’t necessarily show up in travel search engine results.
First, you’re going to search in Google for the airport wiki page for your destination. For example, if you’re planning a Southeast Asian trip and you’d like to fly from Singapore to Bali, Indonesia, search “Bali airport wiki” in Google.
The first result will be the airport’s wiki page. Open the page and scroll down to the “Airlines and Destinations” chart. You’ll see all the airlines that fly to Bali and from where. There are airlines like FlyScoot, Lion Air, and Jetstar Asia which you may or may not have shown up in your flight searches on traditional online booking sites. If not, go directly to each budget airline’s website and price the route you need.
Finding the cheapest flights doesn’t have to be so complicated. Take the resources and tips in this guide. Formulate a strategy to use when looking for the best airfare prices. Once you do, you’ll know for sure you got one of the best deals out of all your fellow passengers!
