Skiplagging, also known as "hidden-city ticketing," is not illegal in the criminal sense, but it is a major violation of an airline's Contract of Carriage. In 2026, courts (including a significant federal ruling in Texas in 2025) have generally upheld that websites like Skiplagged can legally show these fares under "fair use" laws. This means you won't be arrested or charged with a crime for skipping the final leg of your flight. However, the civil consequences from the airlines can be severe. If an airline detects a pattern of skiplagging, they have the right to cancel your return flight without a refund, void your frequent flyer miles, or even permanently ban you from flying with them. Logistically, you also cannot check bags, as they will be sent to the final ticketed destination, not your stopover city. While it is a popular "travel hack" to save money, it is a high-risk strategy that requires you to fly only with a carry-on and avoid linking your loyalty account. Airlines have become increasingly sophisticated in using algorithms to catch "no-shows," making it a practice that should be used sparingly and with full awareness of the potential for a lifetime ban.
