Momondo Flights – the ultimate guide to cheap plane tickets

What is Momondo?

Momondo is a free travel search engine that compares flights, hotels and rental cars. It sells nothing itself and charges the traveller no commission: it searches hundreds of airlines and online travel agents at once, then redirects you to the seller’s website where you complete the booking. Momondo was founded in Denmark and is nowadays part of the same travel group as KAYAK. The website and the Momondo app are both free to use.

How does the Momondo flights search work?

Enter your departure airport, destination and dates, and Momondo lists every available fare, sorted by cheapest, quickest or best. The best score balances price against travel time and the number of stopovers. Colour-coded bars show at a glance whether a fare is low or high compared with the norm for that route. From the results you pick a provider, and Momondo hands you over to that airline or agent to book.

The Momondo features that really save money

Flexible dates. The date picker shows prices for the days around your chosen dates. Moving your departure by one or two days regularly cuts the fare substantially.

Price calendar. The monthly view marks the cheapest days on your route, so you can pick the best outbound and return combination in one glance.

Price alerts. Not ready to book? Set a price alert and Momondo emails you whenever the fare on your route changes. The earlier you set it, the more useful it becomes.

Anywhere search. No fixed destination? Enter your home airport and explore the map of fares to destinations worldwide, sorted from cheap to expensive. Ideal for spontaneous trips on a budget.

Nearby airports. Momondo can include surrounding airports at both ends of your trip. Departing from or arriving at a neighbouring airport is sometimes far cheaper.

Mix and match tickets. Momondo often combines two one-way tickets from different airlines into one itinerary that beats the price of a standard return. Check the conditions of each ticket, because they are separate bookings.

Tips for booking through Momondo

Compare the final price. The cheapest fare in the results is not always the cheapest at checkout once baggage, seat selection and payment fees are added. Compare final prices between providers.

Check the agent before you book. Momondo lists both airlines and online travel agents. Booking directly with the airline usually makes changes and refunds easier; if an agent is clearly cheaper, check its reviews first.

Book ahead and midweek. On most routes the best fares appear a few months before departure, and midweek departures are usually cheaper than Fridays and Sundays.

Watch out with basic long-haul fares. The lowest intercontinental fares often exclude checked baggage and seat selection. Read what is included before you commit.

Momondo or Skyscanner?

Momondo and Skyscanner are both excellent flight search engines, and their results overlap heavily because they query largely the same providers. Momondo shines with its price calendar and colourful fare insights; Skyscanner is known for its “Everywhere” search and clean interface. The winning strategy costs nothing: run your route through both and book the cheapest final price. Our 30 money-saving tips for Skyscanner are covered in a separate guide on this site.

Frequently asked questions

Is Momondo reliable?
Yes. Momondo is a well-established search engine that sells no tickets itself: payment always takes place with the airline or the travel agent it redirects you to. Preferably book with well-known airlines and highly rated agents.

Does Momondo charge fees on flights?
No. Momondo compares prices and charges the traveller no commission. The amount you pay goes to the airline or agent completing the booking.

Are Momondo flights cheaper than booking directly?
Often the prices are identical, but Momondo regularly surfaces agent fares and mix-and-match combinations that are cheaper than the airline’s own website. Always compare the final price including baggage.

When are plane tickets cheapest on Momondo?
Usually when booking a few months ahead, flying midweek and travelling outside high season. The exact moment differs per route; a price alert takes the guesswork out of it.
