A teenager was flying from Gainesville to Charlotte. The price of a nonstop ticket was $255 one-way. But he found that the price of a ticket from Gainesville to New York with a change of planes in Charlotte was just $121. So he bought a ticket to New York and planned to get off at Charlotte and “miss” the connecting flight to New York. But not completing a ticketed trip violates the rules of most airlines, so when airline agents at check-in noted ID documents showing he lived in Charlotte, they confiscated his original ticket and made him buy a new one at a much higher fare. That story has been making the rounds of the air travel blogosphere, and it’s an example of a practice typically called “hidden city” or “point beyond” ticketing.
