Skyscanner

Skyscanner was founded in Edinburgh in 2003 by three engineers who wanted a faster way to compare airfares across European budget carriers. It grew from a small bootstrapped tool into one of the world's most recognisable travel search brands, eventually acquired by China's Ctrip — now Trip.com Group — in 2016 for 1.4 billion pounds. The platform now serves hundreds of millions of users annually and covers flights, hotels, and car hire across almost every country in the world, with particularly strong brand recognition in Europe, Southeast Asia, and the UK.

The core of Skyscanner's product is its price comparison engine, which aggregates live fares from airlines and OTAs and presents them in a clean, filterable interface. Its Everywhere search — letting users find the cheapest destination from a given departure city — became a signature feature that influenced how travel platforms think about inspiration-based discovery. The backend handles enormous concurrent query loads, especially during deal announcement periods when traffic spikes sharply. Month-view pricing calendars depend on successfully pre-computing and caching fare data across thousands of route pairs.

During an outage or API degradation, Skyscanner searches can return partial results, show stale fares that are no longer bookable, or fail to load altogether. The month-view calendar may show gaps or placeholder errors where fare data should appear. The mobile app, particularly popular for its push price alerts, stops sending notifications when the alerting backend is disrupted. Users who tap through to book on a partner site occasionally encounter redirect failures when the deep-link handoff layer breaks down.

Outage.gg collects real-time reports from Skyscanner users worldwide. If searches are timing out, fare data is missing, or the app has stopped sending alerts, the live status page shows current impact from the Skyscanner community.
