There’s no definitive winner when it comes to the best website for cheap flights. Instead, a handful of flight search sites stand out for different reasons, and each has its own strengths. Kiwi.com, for example, is great for finding cheap flights around Europe. Google Flights works well if your travel dates are flexible and you want to keep an eye on prices, while Skyscanner comes in handy when you know you want to get away but haven’t settled on somewhere. And if you’re looking to fly business class, booking directly with the airline is often a good place to start.
Instead of throwing together another list of flight websites, we’ve taken a closer look at what each one has to offer, highlighting their best features and when they’re worth using.
Key takeaways
Kiwi.com: sells you the ticket itself and builds multi-airline routes, including budget airlines such as Ryanair, that other sites don't combine. The Kiwi.com Guarantee on eligible bookings covers a missed self-transfer connection.
Google Flights: compares dates fast with its price calendar and tracks fares for you, then sends you to the airline or a travel site to book.
Skyscanner: ranks every destination by price from your departure airport, so it fits when you know when you can travel but not where.
KAYAK: shows a price forecast suggesting whether to book now or wait. It's a prediction, not a promise, and you book with the seller.
Momondo: lists the booking options for the same flight side by side, including whether bags are included.
Airline websites: sell and control their own tickets, and often run business class and premium economy sales.
Quick Answer (TL;DR)
Kiwi.com is superb for finding budget-friendly European flights and building multi-carrier itineraries, especially if you want to keep all your bookings in one place.
Google Flights suits those who are open to different dates and are happy for the website to track prices for them without searching for the same flights every day.
Skyscanner’s Everywhere feature is suitable when you have the time to travel, but you don’t have a destination in mind.

Cheap Flight Websites Compared
Which website is best for cheap flights comes down to one difference: some sites sell you the ticket directly, while others show you prices and send you somewhere else to book. That decides who handles changes, cancellations and missed connections. Here’s how the best flight website for cheap flights compares with the rest.
| Site | Good fit for | Sells the ticket itself? | Budget-airline coverage | Builds multi-airline trips as one booking? | Protection if a delay breaks a connection | Standout feature |
|---|---|---|---|---|---|---|

| Google Flights | Flexible dates, price tracking | No, sends you to the seller | Varies | No | Depends on where you book | Price calendar and tracking |
| Skyscanner | No fixed destination | No, sends you to the seller | Varies | No | Depends on where you book | Everywhere search |
| KAYAK | Book now or wait | Mostly, sends you to the seller | Varies | No | Depends on where you book | Price forecast |
| Momondo | Airline vs agency prices | No, sends you to the seller | Varies | No | Depends on where you book | Booking options per flight |
| Airline websites | Business class sales | Yes | That airline only | No (own partners only) | Airline’s rules for one-ticket trips | Sales and deal emails |

1. Kiwi.com: Cheap Flights Around Europe and Multi-Airline Routes
Who says you have to fly one airline the whole way? At Kiwi.com, we’re experts at building multi-airline itineraries using carriers that wouldn’t normally work together, budget airlines included, so you can travel on several in one trip and book it all in one go. That opens up the cheapest routes across Europe, plus flights to other continents as well. That’s what makes it the best website for cheap international flights from Europe and the best website for booking cheap flights that mix airlines. Start on Wizz Air from Warsaw , then hop on Vueling to Barcelona .
And if you like flying Ryanair, good news. Kiwi.com is an approved Ryanair partner , so Ryanair fares appear at Ryanair’s own prices.
Don’t forget to make use of our ‘Anywhere’ and ‘Anytime’ search options as well. No specific destination, no fixed dates, no problem. These features will show you what’s out there, giving you plenty of inspiration for your next trip, which is how you find cheap flights to anywhere . There’s also an option to search with carry-on bags included, and sort the results by price.
To try it:
- Leave the destination as Anywhere.
- Set your dates to Anytime or a month.
- Add a carry-on bag and sort by price.
The one thing to watch out for is self-transfer routes. Because you collect your bags and check them in again, leave enough time between flights: 1 to 3 hours for domestic routes, or 2 to 6 hours for international ones. If a delay still makes you miss the connection on an eligible booking, the Kiwi.com Guarantee gets you a replacement flight or instant Kiwi.com Credit. Kiwi.com paid out more than €10.4 million in instant credits and refunds in Q2 2026. If you’re new to this way of travelling, see how self-connecting flights work .

2. Google Flights: Price Calendar and Tracking
When your dates aren’t set in stone, Google Flights can be useful. Pull up the date grid, compare the prices, and book whichever day comes out cheapest. Also set up cheap flight alerts to track fares for a few weeks before you commit to anything. It’s free, quick, and allows you to stay on top of the routes you’re interested in.
To try it:
- Open the date grid or price graph.
- Pick the cheapest day.
- Turn on price tracking.
The main drawback is that you can’t actually buy tickets from Google. It redirects you to the airline or a travel site to complete the booking, and that seller handles any changes.
3. Skyscanner: Everywhere Search for Open Destinations
So, your dates are locked in, but the location is yet to be decided. Skyscanner’s ‘Everywhere’ feature could work for your situation. It’s basically a window into all the places you can fly to with Europe’s budget airlines, from Ryanair to Wizz Air and easyJet.
Enter your dates, and it ranks every place by price from your departure airport, so you see the cheapest places straight away.
To try it:
- Choose Everywhere as your destination.
- Pick the cheapest month.
- Sort destinations by price.
Skyscanner compares prices rather than selling tickets. When you find a route you like, you’ll need to head to a third-party website to buy the ticket. If flexible dates are your priority instead, see how to search with flexible flight dates .

Read the guide4. KAYAK: Price Forecast Before You Book
KAYAK is next on the list. If you’re still figuring out your plans, use their filters to explore your options: choose your bags, add layovers, and pick different airports to get results that match what you’re looking for.
Get started by searching on the website, then look at the forecast that sits over the results. You’ll see whether it suggests waiting or booking the fare straight away. Don’t just base your decision on this, though. It’s only a prediction, and even KAYAK admits that on its website (we take a closer look at these tools in ‘Do price trackers really work?’ ).
To try it:
- Run your search.
- Read the forecast above the results.
- Set a price alert if it suggests waiting.
As with most comparison sites, you’ll usually be sent to another website to book.
5. Momondo: Airline and Agency Prices Side by Side
Momondo is a site to keep on your radar for when you suspect an agency might have a cheaper fare than the airline. A single search shows you the different booking options, along with whether bags are included in the price. That way, you’re seeing the full picture and won’t get caught out by hidden charges (see which fees to check before you book ).
To try it:
- Open a result.
- View all booking options.
- Check that bags are included before you click through.
Something a lot of people don’t realise is that Momondo, KAYAK and Cheapflights are all Booking Holdings brands . If you look at these three, you’re more than likely going to see the same flights and prices over and over again. For a proper comparison, check another company’s website, such as Kiwi.com, just to be safe.
6. Airline Websites: Business Class Sales
If travelling cheaply isn’t your thing, business class might be more your style. You’ll usually find business class and premium economy deals on full-service airline websites such as LOT, which have cabins designed for travellers willing to spend a bit extra. Watch for their sales, and you might find yourself turning left when you board next time. For business class, the best website for cheap business class flights is often the airline’s own.
To keep track of specific business class deals, sign up for the airline’s emails and check their sales page now and then. Also, it’s easier to find different offers on their site by searching across different dates, since they sometimes sell seats at a lower price when there isn’t as much demand.
Booking with one airline can also make things easier if something goes wrong with your flight. You’ll only need to deal with one company, rather than coordinating with multiple carriers over refunds.
If there’s one area where airline websites fall short, it’s that they only show flights operated by that airline and its partners. You won’t find other carriers there, and they usually don’t offer low-cost combinations. That’s where Kiwi.com wins for economy and multi-airline trips. For premium cabins, though, the airline’s own website is worth a look. See every flight class explained .
Which Cheap Flight Site to Use, by Trip Type
| Trip type | Start with | Cross-check with |

Best Website for Cheap Flights FAQs
What is the best website for cheap flights?
It depends on what you need. Kiwi.com is the go-to for flights around Europe. Google Flights makes it easier to find plane tickets when your dates aren’t overly strict, and Skyscanner is a good starting point when you have no idea where you want to travel. Use the flight site picker above to help you choose.
Is it cheaper to book directly with the airline?
Sometimes, particularly if you’re only flying with one airline. That said, most carriers won’t show you cheaper routes from other airlines unless they’re official partners. The easiest way to find out is to add your bags to both options and see which gives you the lower final price.
Is Google Flights cheaper than booking with the airline?
Not necessarily. Google Flights doesn’t sell the plane tickets. It only shows you the options they have available. When you click through, you pay whatever the airline or booking site charges, not a price set by Google. So check the options it shows you properly before you book.
What is the best website for cheap long-haul flights from Europe?
For long-haul trips from Europe, Kiwi.com often uncovers cheaper routes by pairing a short flight to one of the major hubs with a separate long-haul ticket. If you want to compare dates, Google Flights and Skyscanner are both good for that.
Does incognito mode make flights cheaper?
No, that’s a myth. Incognito mode doesn’t cut airline fares. Flight prices rise and fall based on customer buying behaviour and how many seats are left, not because your browser is being tracked. You’re better off setting up price alerts and keeping an eye on the prices yourself.
