momondo review

momondo is a flight and travel search engine whose App Store listing names KAYAK as the developer, and it shares many of KAYAK's tools. It searches hundreds of travel sites at once and filters the results by what matters to you. For bargain hunters, the Anywhere search suggests destinations you may not have thought of, and momondo Explore shows where your budget can take you. Price Alerts track drops on flights, cars and hotels, the flight tracker warns about changes and connections, and the Trips tool keeps confirmations and boarding passes available offline. The app also has the same camera tool for checking carry-on size. Because momondo and KAYAK come from the same company, running both searches may not surface many different fares, so pair momondo with Google Flights or Skyscanner for a wider view. It also books through third parties, so the seller handles any changes or refunds.
