Frequent flyers take note: American Airlines tickets are no longer available on Orbitz. US Airways, which recently became part of American, will take down the flights from Orbitz as well starting September 1. Reservations that were already made on Orbitz will be honored, but changes must go through American Airlines or US Airways directly. Orbitz has been collaborating with dozens of large airlines in the world for 15 years. It charges a fee for listing flights and American feels the partnership is becoming costly. American Airlines president Scott Kirby said, "We have worked tirelessly with Orbitz to reach a deal with the economics that allow us to keep costs low and compete with low-cost carriers. While our fares are no longer on Orbitz, there are a multitude of other options available for our customers." This is not the first time American has decided to pull the tickets from Orbitz. In 2010, American left Orbitz in an effort to gain control over passengers' incidental purchases, but it later came back. Time will tell if American will return again.
