Flight skipping, also known as "skiplagging" or "hidden-city ticketing," is the practice of booking a flight with a layover in your true destination and then walking away from the airport during that layover, skipping the final leg of the journey. This is often done because airlines sometimes price multi-segment flights (e.g., NYC to London to Paris) cheaper than a direct flight to the hub city (e.g., NYC to London). While not illegal, it is a major violation of the airline's Contract of Carriage. In 2026, airlines use advanced algorithms to detect "no-shows" on the second leg; if caught, the airline will immediately cancel the remainder of your itinerary, including any return flights on that ticket. Furthermore, you cannot check bags, as they will be sent to the final ticketed destination (e.g., Paris), not your stop-off city (e.g., London). Frequent use of this tactic can lead to the permanent suspension of your frequent flyer account and the forfeiture of all your accumulated miles, making it a high-risk strategy for serious travelers.
