A federal jury has ruled in favor of American Airlines Group in a long-running lawsuit accusing Sabre Corp. of charging excessive fees and suppressing competition but awarded the airline just $1 in damages. The antitrust case had originally been brought by US Airways in 2011, two years before it merged with American. US Airways had alleged that Sabre impeded travel agents and others from using less expensive alternatives for booking seats, and imposed an unduly restrictive distribution agreement.  Jurors found that Sabre harmed the carrier by willfully maintaining monopoly power, but found a lack of proof that Sabre unreasonably restrained trade through the challenged contract. “We are pleased and gratified with this landmark verdict,” American said in a statement. “We expect this decision to discourage further misconduct by Sabre and bring needed competition to airline distribution.” Sabre said it was disappointed with the verdict on the monopolization claim, but that the $1 award was “commensurate with the evidence presented.” Sabre said it was pleased with the verdict on the distribution agreement.
