American Airlines announced Tuesday that it is pulling its fares from popular travel website Orbitz.com “effective immediately” and also will pull its US Airways offerings next week. “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,” American Airlines President Scott Kirby said in a statement. The issue at hand was fees the travel site charges for posting and selling the airfares. For its part, Orbitz said it won’t be hurt by the move. “Our sites offer hundreds of airlines which are eager to capture the revenue American is choosing to forego,” it said in a statement. In 2010, American pulled its fares in response to disagreements over selling extra services like WiFi and meals.
