Which site has the cheapest flights

And while many of these OTAs power their searches using the same fare data provided by ITA Software now owned by Google , you can still find substantial discrepancies in results from one to the other. Another curveball? You may find the set of features offered by one site meets your needs better than another.

Part of the Kayak network, Danish-based metasearch site Momondo is a great option for international flight searches, thanks to its inclusion of lesser-known regional budget airlines combined with other carriers. Another major distinction, domestic searches include Southwest flights whereas other sites do not. You still have to click through to Southwest.

Advantages: For a broader view of flight options, Momondo lists unusual routings the other sites tend to miss, including Southwest. What our terms mean There are a few things to keep in mind before you search. There are booking engines that find prices themselves Expedia, Priceline, Hotwire. And then there are aggregators—sites that do not book tickets but instead search dozens of booking engines, airfare sites, and OTAs online travel agencies and compile the results in one place; you then click through to the one of your choice to make the actual purchase.

Some of the booking sites these aggregators show you are better than others. As with any unfamiliar company, always do a quick BBB. Southwest annoyingly does not allow its results to be aggregated or sold through third party OTAs. Only twice did Priceline find the lowest fare in our tests— but that low fare was also matched by many sites that outranked it.

Most of its results muddled around in the middle or back of the pack at best, and it found the worst fares three times. How the mighty have fallen. Now that it owns Travelocity and Orbitz , Expedia runs all of the former Big Three booking engines, so you now get the exact same results on all three. Several years ago, Expedia was safely in the middle of the pack. Now it has slipped to the bottom for its utterly middle-to-end-of-the-road search results.

It never, not once, found the best price, and only three times out of 25 did it find a next-to-best price twice, it was for the NYC-LAX flights. On the other hand, it was in last or next-to-last place in seven searches.

The results from this smaller discount OTA were all over the place. It performed the strongest of any on our list for several last-minute international fares, so it can be handy for that. This can save you money, but be sure to compare prices before you book. Expedia charges variable booking fees and they are not always the same fees that Travelocity charges. However, the savings might be worth it. TripAdvisor is known for its hotel reviews, and now travelers can apply their ratings to airlines, plus search for airfare on TripAdvisor Flights.

TripAdvisor Flights also has some helpful search options up front, like a checkbox for prioritizing nonstop flights. Skyscanner is a popular metasearch site that works with hundreds of other travel providers to find the best fares.

When you enter your departure and destination airports, the dates field brings up a calendar with prices pre-populated. This is a helpful feature for immediately honing in on the travel dates with the best prices if and when your dates are flexible.

OneTravel also offers different and in my opinion, sometimes worse itineraries than most at the top of its results page. Many highlighted itineraries, upon closer inspection, include an extra stop. Travelzoo is quite different from the other sites listed here. Instead of booking specific itineraries, you can search broad timelines this week, next month, this summer, etc. This makes Travelzoo a good fit for people with a budget and time frame, but no firm idea of when or even where they want to go.

The downside is that if you do have specific plans in mind—for example, you need a flight to Omaha in March—Travelzoo is not likely to be helpful.

Google Flights is a powerful, simple metasearch site that comes free of ads and distractions. After you enter your departure and arrival airports, the calendar pre-populates with prices so you can target dates with lower fares OneTravel uses this tool. Once you have your results, you can track fares on your selected dates and receive updates by email. Best Feature: Instead of putting in a certain city as a destination, you can put in a larger region such as Europe or South Africa.
