In Europe, Skyscanner&#x27;s big advantage is that they have price data from low-cost carriers whose fares &amp; inventory are not normally available to GDSes. They&#x27;ll show you prices for people like Wizz Air, EasyJet, Ryanair, etc. who might not show up in a matrix.itasoftware.com search.<p>Skyscanner can also construct somewhat of surprising itineraries by piecing together tickets on multiple separate LCCs that involve non-protected transfers, which is something that other price search engines (Hipmunk&#x2F;Kayak) or online travel agencies (Expedia&#x2F;Orbitz) don&#x27;t really do. Most fare engines won&#x27;t say &quot;hey, if you&#x27;re trying to get from London to Ljubljana, how would you feel about taking Easyjet LGW-BRU and Adria BRU-LJU?&quot; — but Skyscanner will.<p>And they have a fairly cool &quot;I want to go from [x city] to [anywhere]&quot; web UI that will show you, for a given weekend, what are the cheapest countries&#x2F;cities you could visit? The UI is very good, arguably a bit better than the Google Flights fuzzy date&#x2F;trip search.<p>It&#x27;s a great tool for exploring European fares. But I&#x27;m not sure how they make money — there&#x27;s not a lot of revenue in air bookings.
