You can physically skip a portion of your flight—a practice known as "Skiplagging" or "Hidden City Ticketing"—but it comes with significant risks and penalties in 2026. Airlines strictly prohibit this in their "Contract of Carriage." If you skip the first leg of a multi-city or round-trip ticket, the airline will automatically cancel every subsequent leg of your journey, including your return flight. If you skip the final leg of a one-way trip, you won't lose any further flights, but there are other "pro" issues: you cannot check a bag, as it will be sent to the final ticketed destination, and you risk having your frequent flyer account frozen or being banned from the airline if you do it repeatedly. In 2026, airlines use advanced algorithms to detect "hidden city" patterns. While it can save money on paper (e.g., a flight from NYC to DC to Miami being cheaper than NYC to DC), the potential for being stranded or losing your "Elite Status" makes it a high-risk gamble. Always fly with only a carry-on if you attempt this, and be prepared for the airline to charge your credit card the fare difference if they catch the violation.
