Skyscanner

Rather than selling most tickets itself, Skyscanner works as a flight comparison engine that scans airlines and online travel agencies and then sends travellers to the seller to complete the booking. Its search tools suit flexible planners: the Everywhere option shows fares to any destination from a chosen airport, and whole-month views help identify cheaper travel dates. Price alerts notify users when tracked routes change. For some fares, a booking can be completed without leaving Skyscanner, though the ticket is still issued by the airline or agency involved. Because the lowest result may come from a smaller agency, buyers should check who they are actually paying, that seller's service record and how changes are handled. Skyscanner is part of Trip.com Group, and it also offers hotel and car hire search.
