Airlines, of course, have a huge problem with this. According to Bloomberg, they told Orbitz that the practice is fraudulent and that they'll void a ticket without refund if they catch travelers doing it. They reason that it exploits the hub-and-spoke system, causing public safety and logistical problems with passenger counts. Other experts say airlines don't like it because it costs them money, and American Airlines even threatened to raise fares due to increased use of the trick. United and Orbitz are seeking a court order to halt the practice, and while Skiplagged had no comment, it's now soliciting donations from users to fight the suit in court. So far, it's two-thirds of the way to its goal.
