how to use momondo (2026) — find the cheapest flights, honestly reviewed

tldr: momondo is a flight metasearch engine that searches 900+ sources — including small OTAs that google flights and skyscanner miss. it often finds the cheapest fare, but the trade-off is slower search speed and the risk of booking through third-party OTAs with varying customer service quality. the best strategy: search google flights first for dates/routes, then cross-check momondo for a potentially cheaper price, then book on the airline’s own website unless the momondo OTA price is $30+ cheaper.

what momondo is (and what it’s not)

momondo is a metasearch engine for flights, hotels, and car rentals. it does NOT sell tickets directly. it aggregates real-time prices from 900+ airlines, OTAs, and booking sites, then redirects you to the actual provider to complete the purchase.

the key difference from google flights: momondo searches smaller, less-known OTAs that google doesn’t — travelberry, fareboom, bargainairticket, dohop, and dozens more. these smaller OTAs sometimes access unpublished agency fares that undercut airline website prices.

ownership: founded in copenhagen in 2006. acquired by booking holdings (the $100 billion company behind booking.com, priceline, kayak, and agoda) in 2017 for $550 million. now managed by kayak.

revenue model: momondo takes only 25% of the affiliate commission when you click through to a booking site. this is a low cut by industry standards, which incentivizes virtually every OTA to list on momondo — and that’s partly why it surfaces cheaper fares.

why momondo prices are sometimes cheaper

three things work in momondo’s favor:

1. low commission = lower OTA prices. momondo’s 25% commission cut (vs higher cuts elsewhere) means OTAs can afford to price lower and still be profitable.

2. smaller OTAs that nobody else shows. google flights and kayak index the big players. momondo also lists small, scrappy OTAs that are willing to work on thinner margins.

3. unpublished agency fares. airlines offer special discounted fares to travel agencies with conditions like “don’t undercut our website.” some OTAs on momondo break those rules. savings vary by alliance: star alliance airlines (united, air canada, lufthansa) show the biggest savings. skyteam carriers (delta, air france) show minimal savings.

real example from testing: atlanta to amsterdam, feb 12-19. google flights: $596. momondo found the same flights for $559 through bargainairticket — $37 cheaper.

how to search flights on momondo — step by step

1. go to momondo.com (defaults to flight search)
2. select trip type: round-trip, one-way, or multi-city
3. enter departure city, destination, dates
4. set passengers and cabin class
5. optional: toggle flexible dates (+/- 1-3 days)
6. click search
7. wait 30-60 seconds — momondo is slower than google flights because it searches 900+ sites simultaneously
8. review results — all fares shown include taxes
9. use filters on the left sidebar (stops, airlines, times, booking sites)
10. check the price calendar above results for cheaper nearby dates
11. click “prices” on any flight to see rates across different booking sites for the same itinerary
12. click through to the booking site to complete purchase

the “prices” button is key. for any given flight, momondo shows you prices from multiple OTAs. the difference between the cheapest and most expensive OTA for the same flight can be $50-100. always check all options.

the features most people don’t use

flight insight tool

momondo’s most underrated feature. it analyzes six variables that impact flight price:

1. days in advance — how far ahead to book for the best price
2. time of day — morning, afternoon, or evening departures
3. day of week — which departure day is cheapest
4. seasonality — cheapest months to fly
5. specific airport — if the city has multiple airports
6. airline — which carrier is cheapest on this route

shows results as a pie chart of trends plus specific cheapest/most expensive examples. available on 400+ set routes. this is genuinely useful data that neither google flights nor skyscanner offers.

price calendar

appears above search results. shows cheapest fares across dates in a calendar/graph format. useful for spotting the cheapest days to fly. not as powerful as google flights’ date grid, but helpful for quick scanning.

explore / anywhere search

enter your budget, select trip type, and see everywhere you can fly. map overview with estimated prices. can filter by budget, temperature, and activities (beaches, skiing, golf). good for inspiration when you know WHEN but not WHERE.

price alerts

enable on the results page after any search. sends email up to twice a week with price change notifications. ios app supports push notifications. can create alerts for unlimited routes.

mobile app features

the momondo app has two features the website doesn’t:

• AR bag measure — use your phone camera to check if your carry-on fits airline size requirements
• offline access — save ticket confirmations and reservations for offline viewing

the honest pros and cons

pros

• searches 900+ sources including small OTAs that competitors miss
• often finds the absolute cheapest fare — some tests show 95% success rate
• shows southwest airlines results
• 100% free, no booking fees added
• flight insight tool provides unique pricing transparency
• multi-city search works well
• claims no cookie-based price inflation

cons

• slow. 30-60 seconds per search vs near-instant on google flights
• bait-and-switch is real. prices shown on momondo sometimes jump higher on the OTA checkout page. momondo acknowledges this is “an ongoing battle with suppliers”
• third-party OTA risk. if your flight gets canceled/changed, you’re dealing with the OTA (often a small company with limited phone support), not the airline
• no direct booking. always redirected to a third party
• limited date flexibility. no equivalent of google flights’ date grid or skyscanner’s “whole month” view
• ghost fares. occasionally shows flights that don’t exist at the listed price when you click through
• user reviews are mixed. trustpilot: mixed. pissedconsumer: 2.1/5. resellerratings: 2.03/5. most complaints involve OTAs, not momondo itself.

is momondo safe?

momondo the company: completely legitimate. owned by booking holdings, a publicly traded $100+ billion company. scam detector gives it a 75.4 trust score (medium-high).

the real risk: the third-party OTAs momondo redirects you to. while listed OTAs are vetted to some degree, customer service quality varies wildly. IATA-regulated agencies sell valid tickets, but getting a refund or rebooking through a small OTA during a flight disruption can be a nightmare.

common complaints:

• price on momondo doesn’t match checkout price on OTA
• ghost fares that don’t actually exist
• poor customer service from smaller OTAs
• difficulty getting refunds when OTA and airline blame each other

the rule: if the momondo OTA price is only $10-20 cheaper than the airline’s own website, book directly with the airline. better customer service, easier changes, full loyalty miles. only use the OTA when the savings are $30+ and justify the risk.

momondo vs google flights vs skyscanner vs kayak

the workflow that gets you the cheapest flights

1. google flights — explore dates and destinations, use the date grid, set up price tracking
2. momondo — cross-check the same route/dates for potentially cheaper OTA prices
3. skyscanner — verify if budget carriers (ryanair, airasia) offer anything cheaper
4. airline website — compare the direct price. if it’s within $20-30 of the cheapest OTA, book direct.

this takes 5-10 minutes and can save $50-200 on international flights.

tips that actually save money on momondo

1. search google flights first, momondo second

google flights is faster for exploring options. once you’ve identified your ideal route and dates, cross-check momondo for a cheaper price through a smaller OTA.

2. fly on tuesdays

momondo’s own data shows tuesday is the cheapest day to fly.

3. search for 1 passenger even when booking for a group

multi-passenger searches sometimes show inflated fares (one test showed a 34 EUR/person difference). search for 1 ticket, find the best price, then book individually.

4. check the “prices” tab for each flight

the same flight can cost $50-100 different across OTAs. always compare all providers for your chosen itinerary.

5. vet the OTA before booking

google the OTA name + “review” before entering your credit card. if the OTA has terrible reviews, the $30 savings isn’t worth the risk.

6. use the flight insight tool

available on 400+ routes. it tells you exactly when to book, what day to fly, and which airline is cheapest. free data that no other platform provides.

7. set price alerts and wait

enable alerts on 3-5 route variations. check back when momondo emails you a price drop. don’t buy on the first search.

8. use flexible dates

toggle +/- 3 days on both departure and return. even 1-day shifts can save significantly.

momondo for indian travelers

momondo has a dedicated india site (momondo.in) with INR pricing. it searches domestic indian carriers — indigo is the most popular airline among momondo users for international flights from india (52% of bookings).

where momondo helps in india:

• international flights from india to europe and the US — this is where the small OTA savings are most significant
• star alliance routes (air india’s alliance partners: united, lufthansa, singapore airlines) show the biggest price gaps

where momondo doesn’t help much in india:

• domestic indian flights — cleartrip, makemytrip, and booking directly with indigo/air india usually have better inventory and pricing
• most of the smaller OTAs that give momondo its edge are US/europe-focused

popular routes from india on momondo: delhi to srinagar, aurangabad, patna. cheapest flights from delhi start at INR 1,152 (to bathinda). international: cheapest from india start at INR 3,600.

bottom line for indian travelers: use momondo primarily for international flights. for domestic india, stick with cleartrip, makemytrip, or direct airline booking.

who should use momondo

use momondo if:

• you want the absolute lowest price and are willing to book through smaller OTAs
• you’re flying star alliance airlines (biggest savings)
• you’ve already identified your route/dates and want to price-check
• you want the flight insight tool data
• you’re booking multi-city trips

use google flights instead if:

• you need speed
• you’re exploring dates/destinations
• you prefer booking directly with airlines
• you want AI-powered search or price guarantee

use skyscanner instead if:

• you’re completely flexible on destination
• you want to search an entire month at once
• you’re flying budget european/asian carriers

use all three if:

• you’re booking an international flight and saving $50-200 matters to you
• 10 minutes of cross-checking across platforms is worth the savings
