Momondo

Momondo is a flight and travel comparison site, part of Booking Holdings through the Kayak group, that searches airlines and booking sites and sends travellers to the seller to complete the purchase. It presents results with a clean layout and visual tools: a price calendar, flexible date search and tabs that sort options as cheapest, quickest or best overall by its own scoring. Price alerts track routes for changes. Momondo shares much of its underlying search technology with Kayak, so results can be similar, but some travellers prefer its interface. It is free to use and also covers hotels and car hire. As with other metasearch tools, the deciding factor is the final seller: check the agency's reputation, the total with baggage, and its change and refund policy before committing.
