American Airlines is trying to crack down on a travel hack. This week, American sued a website that sells tickets that let people save money by exploiting a quirk in airline pricing. Consumers book a flight with at least one stop, then get off the plane during the layover and skip the second leg of the flight. Sometimes it's cheaper than a direct flight between two cities. In the lawsuit, American accuses travel website Skiplagged of tricking consumers and reselling American tickets without the airline's approval.
