Another travel company is jumping into the fight with American Airlines over ticketing information.
Sabre Holdings said on Wednesday it is moving to end its agreement with American, and will make American fares harder to see in its displays. Sabre runs a computer system that allows travel agents to see flight and fare information.
Sabre also said it is removing discounts it previously gave to American.
Sabre says the move does not affect its online booking site, Travelocity.
American pulled its flight listings from Orbitz last month when the two companies couldn't agree on a new contract. Online booking site Expedia dropped American flight listings over the weekend.
American, a unit of AMR Corp., did not immediately have a response to Sabre's move.
