Yes, Skyscanner is a highly legitimate and reputable travel metasearch engine that has been operating since 2003. It does not actually sell flights directly; instead, it aggregates data from thousands of airlines and online travel agencies (OTAs) to help you find the lowest prices. Because it is a search tool, its "legitimacy" is rooted in the accuracy of its data and the quality of the partners it links to. While Skyscanner itself is trustworthy, users should always pay attention to the specific booking site they are redirected to. If Skyscanner sends you to a major airline's official site, it is 100% safe. If it sends you to a lesser-known, third-party OTA with a low star rating, the booking process may be more difficult to manage if you need a refund or change. In 2026, it remains one of the most-used travel tools globally due to its "Everywhere" search feature and its transparency regarding additional fees like baggage and seat selection.
