The Best Sites For Finding Cheap Flights

Last updated: March 18, 2019

The best sites for finding cheap flightsLet’s face it, trying to find a good deal on airfare can be intimidating!

There are so many sites to look at – from airline sites, to online travel agencies, to third party comparison services. Ultimately, you’re left wondering if you're getting the best price. And that's not a good feeling.

The best place to start is always with comparison websites that don’t actually let you book directly. This is because not only do they have access to the same inventory as the others, but they also partner with a wide array of online travel agencies to ensure you get the absolute lowest price.

In fact, most sites should have very similar prices and inventory because they all use a small shared set of backend systems. Therefore, the biggest savings come when you either find an interesting booking that is a mish-mash of multiple airlines or one of the online travel agencies decides to get aggressive on their pricing and pass on some of their usual profit to you.

Common Features

Most of these sites offer a core set of features that everyone has come to expect when researching airfare. Unless otherwise mentioned, they all had:

  • Great filters.
  • Up to date prices.
  • Easy to use calendar.
  • Price drop notifications.
  • Apps for mobile devices.
  • Multiple booking partners.
  • Easily swap between dates.
  • Country and currency selection option.

How Ranking Were Determined

Price was the most important factor in determining the rankings. If prices were nearly identical, then I also considered the accuracy of prices listed along with ease of use and number of useful features each site had.

Momondo really won in a landslide on all accounts because they always had the lowest accurate prices and their feature and usability are unmatched by their competitors.

I try to search for a round trip YUL - SSA 7 dec - 29 march in momondo

I have pay 939 CAD tx included

the site fares was in the order of 1300 CAD and was incapable of find any flight. I use for that and have lower price than the airline ( air canada) .

Priceline give me a slight better price but when I went to book it they say we can't fInd it.

I use to this similar travel every year, and every year the best price it's with a different airline.

Have you already try the bet your own price on priceline? do you know if that work?

I've used Priceline extensively for booking hotels but not so much for flights. Booking a flight is more complicated and important than booking a hotel, so I'm more hesitant to use the Name Your Own Price service for flights although I am interested in trying it sometime.

From what I've read, discounts aren't nearly as high on flights booked this way and it may not be worth the added restrictions to do it. Let me know if you try it and how you make out.

For sure - that's a great site. Those are for special sales and deals - this article is geared towards finding the best price on a particular day/time/route.

I've been using for flight deals and can't recommend them enough!

FWIW, I've perused the aggregator sites and true, some good, some not so, based on the speed, features, results, etc.
In the end, I have ended up booking directly with Porter, AC, KLM or AF at either same price as the "cheap sites" or only a smidgen more. (and sometimes less!)
Seems that I get that one-on-one personal contact and don't have to deal with a middleman.

Another twist is that sites such as iTravel2000, Red Tag, Travel Nation Canada do not have the option to search beyond Economy. (this may have changed recently)

That being said, if you find the destination, flight, time, date combo that works, ring up the site call centre as they have a backdoor into the airline rez systems to get the details on that Prem Econ or Biz seat you crave.
Or just go the airline in the first place and earn some goodwill brownie points with them.

Do you have experience with ita matrix? When I see a good sale, I use it to see what days are better. It also gives the option of looking at nearby airports. So when I go to Europe, I look for an initial destination and another one to return from.

Interested in knowing your thoughts on it.

I recently subscribed to and am a premium member over there. The guy has a newsletter and he sends out great deals whenever he can find them (pretty often). I would check that out if you don't have time to search for them yourself.

They seem to start at 40% off of a standard rate, which is a great deal, but some deals are even better. I'm not sure what sites he uses or what he has set up on the backend, but whatever it is it works.

Good day Mr. W.
As a follow up to my comments of last year, I revisited this topic and as of today, I ran my parameters through each of the sites listed. Being almost 3 years after your trials, I expected things to change and my observations may reflect that.

Based on my input of: YYZ > BRS - 06/12/18 > 06/17/18 - 1 Adult - Prem. Econ. - 1 stopover - <4 hrs layover, I found that:

Momondo, was almost $1000 over the fare I did find. (that was Expedia, within your picks, but found cheaper from some other sites I stumbled across, may have been iTravel2000)

Cheapseats, maybe, but very poor flight options.

Skyscanner, again very pricey.

Kayak, was SO slow and plodding along, I just gave up and closed the window. (must have been all the paid adverts that had to load every time you changed a filter. Stupid)

Farecompare did not impress me either.

Hipmunk, had a very nice interface & results display, but the lack of the PE class option (despite it showing in the price results) makes them DOA.

Google Flights, dead easy to use and very fast, but after getting PE flight costs, then without changing any filters, looking at Biz and then going back to PE came back with "No Results". Giving it a second chance found good results and a tad less expensive than the sites listed above.

SkipLagged, very nice results presentation, but again, no option to select level, they assume you are a cheap bugger and will always fly cattle class. So, DOA to me.

Expedia, was not hard to use and the results, once filtered, were price-wise much better than the rest. (interesting how they ask you to select filter options instead of de-select as the other sites do) However, they could not find 1 Stop return flights were the other sites did. But the flight details were very good, showing flight time, layover, aircraft type, class, meals and best of all, confirming baggage allowance and/or charges.

Notably, I was finding results from these sites and others that when running the same data within the actual airline sites, they came back with "we don't fly there" when they apparently do, even if it's with a partner. ie: AirCan, Icelandair, Aer Lingus, BA.....weird.

FWIW, I found it interesting on how many sites use the same software format (all in the same family perhaps?) and the over-hyped CheapOair proved to suck large. Annoying and pricey.

In the end, unless you have copious amounts of time to spend searching, there are SO many sites out there (and some are quite bogus / scammy apparently) you could drive yourself to madness. Ah, the world we live in, yes?

Congrats on your excellent job !

On another note, I‘d kindly like to add a constructive critique ? I found a little offensive the term “cattle class”. I believe everyone in Canada has the right fly either for business or pleasure, Fortunatly, we are proidly one of the few countries in the world that does not reproduce in a large scale the terrible wwalth concentration that we see in most global south countries and parts of the US. As such, I always proudly reproduce the sentence “the world needs more Caanada”. Calling “cattle class” a place where many fellow Canadians are able to travel is far from being a value of this country, Therefore, as a very proud Canadian-even though I don’t usually travel economic- I take personal ofense with the term ‘cattle class” and I am sure most of my compatriots will agree with me. Prejudiice does not help us to build a better world. Never.
