Travel.CimpleO

Comparing flights one airline site at a time is slow, and most travelers only ever check the two or three names they already know. Travel.CimpleO puts 850+ airlines and 250,000+ flight providers behind a single search, with results rendering in place instead of redirecting to a separate booking domain.

For travelers without a fixed destination, a “popular from your city” panel surfaces live fares out of their detected departure airport before they’ve typed anything — turning idle browsing into a search. A companion banner routes delayed or cancelled flights to a EU261/UK261/Turkish/Canadian compensation claim worth up to €600, something most travelers wouldn’t otherwise think to pursue.

The page itself is static — no backend, no database — with one small serverless function keeping the destinations panel’s API credentials off the client. English and Russian, plus 15 currencies, are handled through a page-level switcher rather than separate builds.
