momondo review

momondo sits just behind KAYAK because the US App Store lists KAYAK as its developer and its feature list mirrors KAYAK's: it searches hundreds of travel sites, filters results, and offers momondo Explore for budget-first searches and Price Alerts for tracked trips. Its Anywhere search suggests destinations you have not considered, which suits travelers who choose a trip by price. After booking, the Trips tool holds confirmations offline, tracks flights and sends gate change alerts, and the app also measures carry-on bags with the camera. momondo has the highest App Store rating in this list at 4.9, though from 40K ratings, far fewer than KAYAK's 500K. The main reason to choose it over KAYAK is preference for its layout; because both run on the same engine, checking both rarely changes the cheapest fare. We compared documented features and published information; we did not book test trips.
