For years savvy travelers have saved loads of money by booking one-way flights and not completing their itineraries. These bookings are referred to as hidden-city or throw-away ticketing. Historically there has been little or no recourse against said travelers, except canceling the remainder of their itinerary (which was not being utilized anyway).
Passengers are willing to pay more for direct flights, therefore airlines charge more for non-stop flights than a flight with a connection in that very same city. For example, a flight from Los Angeles to New York with a layover in Cincinnati is less expensive than a direct flight from Los Angeles to Cincinnati. As long as passengers carry their luggage on, they are able to book a less expensive fair and get off at the connection. These bookings have become more prominent in recent years with websites such as Skiplagged.com that were specifically designed to help find such fares.
This week British Airways has announced they will fight back against such fliers. According to Head For Points:
British Airways is not the first to take action against these types of one-way flights. Recently, United Airlines and Oribiz have filed a lawsuit against Skiplagged.
