There are many cheap flight apps such as Skyscanner, but Skiplagged is different. Skiplagged shows flights with 'hidden' city locations where there is a layover that doesn't show on the itinerary. This means users can legally choose to board or disembark the flight at the hidden layover city. If you have a few date options, Skiplagged has an interactive graph to find the best prices, and the app can also help you find the best deals on hotels and cars.
