The 1st U.S. Circuit Court of Appeals affirmed a trial judge's ruling blocking the airlines' "Northeast Alliance."

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.

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

In May 2023 a federal judge rejected a partnership between American and JetBlue. Today, its lost value is hurting both airlines. But the partnership is not quite dead.

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.

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.
