Skiplagging (or "hidden city" ticketing) is the practice of booking a flight with a layover in your actual intended destination and then simply walking out of the airport during the connection, skipping the final leg. While it can save hundreds of dollars, it is a violation of the "Contract of Carriage" for almost all airlines. In 2026, airlines have become much more aggressive in identifying and punishing this behavior. If caught, the airline will likely cancel the remainder of your itinerary (including your return flight) without a refund. Furthermore, you can lose all your accumulated frequent flyer miles, and some airlines have even sued passengers or banned them for life. There are also logistical risks: you cannot check a bag, as it will go to the final ticketed destination, and if your flight is rerouted due to weather, you might end up in a completely different city. While not illegal in a criminal sense, it is a risky "travel hack" that puts your loyalty accounts and future travel ability at significant risk.
