A U.S. court held that a trial judge correctly found that American Airlines' partnership with JetBlue Airways violated federal antitrust law.

American Airlines keeps trying, but the courts keeps winning. The First U.S. Circuit Court of Appeals in Boston has ruled against American as it tried to overturn the original ruling that disbanded the Northeast Alliance with JetBlue.

A partnership between American Airlines Group Inc. and JetBlue Airways Corp. violated US antitrust law, an appeals court ruled, affirming a lower court decision to end the alliance.

A U.S. appeals court on Friday rejected a bid by American Airlines to overturn a judge's decision that sided with the U.S. Department of Justice and declared that its now-scrapped U.S. Northeast partnership with JetBlue Airways was anticompetitive.

American Airlines lost its appeal to revive an alliance with JetBlue that collapsed after lawsuits succeeded in declaring it anticompetitive, a judge ruled

An effort by the two carriers to work together to compete with Delta and United in the Northeast has been left stalled on the tarmac.
