DALLAS – American Airlines Inc. has filed a lawsuit against Travelport LLC and Orbitz Worldwide LLC accusing them of “exclusionary and anticompetitive business practices,” the airline said Wednesday.

In return, Travelport and Orbitz accused American of bullying tactics and attempting to use the courts “to revive an unsuccessful strategy.”

The lawsuit is the latest development in a dispute over how American will make its fares and other services available online and how it will sell and distribute its tickets. Since late last year, American has pulled all its travel information off Orbitz, which is affiliated with Travelport.

American said in its lawsuit that Travelport “has engaged in anticompetitive conduct to protect its market position from new competition by alternative technologies that are both less expensive and more capable.”

Orbitz called the claims baseless and part of an attempt by American “to adopt an airline ticket distribution model that limits consumer choice and inhibits competition.”
