Intentionally missing the return portion of a round-trip ticket—a practice often related to "Hidden City Ticketing"—can lead to several "High-Fidelity" consequences. First, the airline will immediately cancel any remaining segments on that specific ticket; you cannot miss your return flight and then expect to use a third or fourth leg of the same journey later. While doing this once is unlikely to result in a lawsuit, airlines have become much more aggressive in 2026 at tracking "repeat offenders." Frequent flyers who habitually skip flights may have their loyalty accounts frozen and all accumulated miles confiscated. Additionally, the airline may send a "bill" for the difference between the cheap round-trip fare you paid and the more expensive one-way fare you actually used. Most importantly, if you have checked luggage, it will travel to the final ticketed destination, not where you decided to get off, which can lead to a "High-Fidelity" logistical nightmare. It is generally safer to book one-way tickets if you aren't sure of your return, as this avoids violating the airline's "Contract of Carriage."
