Momondo helps you find cheap flights.
Really amazing user interface with great support for user in comparing the flightsCons:
Should use more flights to compare
used the product, satisfied with their efforts on the productSarah Elson has used this product for one day.
Good UX, feels also more accurate than others with more optionsCons:
I guess there are still few cheap airlines that don't show up on Momondo, but they don't do also on other sites (except airlines own site)
My favourite flight search engine besides Google Flights. Great product, good UX! Pretty popular in Germany at least.Silver Ilves has used this product for one year.
