Purposely missing a connecting flight—a practice often linked to "hidden city ticketing"—carries significant risks in 2026. If you fail to board your second leg, the airline's automated system will immediately mark you as a "No-Show." This triggers a chain reaction: your entire remaining itinerary, including any return flights on the same booking, will be automatically cancelled without a refund. Furthermore, if you are a member of the airline's frequent flyer program, you risk having your account audited, your earned miles confiscated, or being banned from the airline entirely for violating the "Contract of Carriage." Additionally, because your checked luggage is usually tagged to the final destination, it will continue to that city without you, making it extremely difficult (and often expensive) to retrieve. Airlines have become much more aggressive in tracking and penalizing this behavior to protect their hub-and-spoke pricing models.
