Momondo is a mainstay for the cheap flight community. Simply put, it is one of the best flight search engines for getting the cheapest fare possible.
As opposed to better-known sites like Expedia and Priceline, Momondo does not actually sell flights. Instead, Momondo operates as a meta-search engine, scouring hundreds of online travel agencies (OTAs) to find the cheapest possible fare.
Momondo excels in a number of areas:
Here’s where Momondo lags:
Eagle-eyed readers will notice that Momondo’s weaknesses mirror Google Flights’ strengths and vice versa. This is why with many deals, using both sites in tandem is the best strategy.
Best practice when searching for flights is to start your search on Google Flights, find the best route and dates, then check those dates in Momondo to see if there’s a lower price there.
Let’s walk through an example together. Say you’re a romantic, so you’re planning a trip to Europe for Valentine’s Day, but you’re self-conscious about appearing cliche, so you’re thinking Amsterdam instead of Paris.
You start in Google Flights, poke around at various dates, and find flights from Atlanta to Amsterdam for $596 roundtrip from February 12-19.
Pulling up Momondo, you input the exact same route and dates like so:
Remember that Momondo searches usually take an internet eternity (30+ seconds) to complete; big patience is required. You’ll know it’s done when the wheel in the upper left stops spinning and shows this:
Momondo found the exact same flight for $559, a price drop of $37 from Google Flights.
In this case, Google Flights’ $596 fare is sold directly by United and Momondo’s $559 fare is sold by Bargainairticket, a relatively small online travel agency. If you want to book that fare, just click the green “Go to site” button.
The question of whether to book a flight with an online travel agency you may not have heard of is a tricky one; we have a more thorough writeup in our complete guide to online travel agencies (OTAs).
To get more information about a particular flight routing, click DETAILS in the lower left corner. If you’re interested in the flight but don’t want to book with Bargainairticket (or whichever site has the absolute cheapest fare) you can see how much other online travel agencies are selling the flight for by clicking PRICES.
All fares shown include taxes.
Unlike Google Flights where you can set filters anywhere in the search process, with Momondo you can only filter results after you’ve already begun the search.
All the filters can be found on the lefthand side, including number of stops, trip duration, trip times, airports, airline(s) and/or alliance(s), booking sites, economy or first class, price, aircraft, and various other flight characteristics.
