If you skip a leg of your flight—a practice often called "hidden city ticketing"—the most immediate consequence is that the airline will automatically cancel all remaining segments on that itinerary, including your return trip. Airlines use sophisticated software to track "no-shows," and their Contract of Carriage explicitly forbids intentionally skipping legs to save money. Beyond the cancellation of your ticket, you may lose any frequent flyer miles earned on that trip, and in extreme cases, the airline could freeze your loyalty account or ban you from future flights. In 2026, airlines have become even more aggressive in monitoring this behavior. Additionally, you cannot check luggage if you plan to skip a leg, as your bags will be tagged to the final destination on the ticket. If you must skip a flight due to an emergency, you should notify the airline immediately; if you have a valid reason, they may be able to protect the rest of your itinerary, though they might charge a fare difference based on the actual route you end up flying.
