American Airlines and US Airways will stop posting their fares on Orbitz.com after feuding with the travel website about fees, according to the Los Angeles Times.

American Airlines, along with merged US Airways, said it could not reach an agreement over the fees Obitz charges to post and sell airfiares to its website.

"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," said American Airlines president Scott Kirby in a statement.

American Airlines also said it is pulling its listings from Cheapticket.com, which is a subsidiary of Orbitz, The Associated Press reported.

Effective immediately, Orbitz will stop selling American Airline tickets, and it will stop selling US Airways tickets on Sept. 1, according to CNN Money. Reservations that were already made on Obitz.com will be honored, however any changes will have to be made directly with American Airlines or US Airways. 

But Orbitz does not seem to be fazed by losing the business of American Airlines.

"Our sites offer hundreds of airlines which are eager to capture the revenue American is choosing to forego," Obitz spokeswoman Marita Hudson Thomas said in a statement. "...we will continue to show our customers a broad range of flight options to thousands of destinations in the U.S. and worldwide."

However, AP reports shares of Orbitz Worldwide Inc. had fallen almost 5 percent Tuesday.

This isn't the first time American Airlines has feuded with Orbitz. The airline pulled its airfare listing off the website once before in 2010 after arguing over American's efforts to gain more control of extra passenger services it offers to its traveling customers, according to the LA Times.
