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

The original premise of the alliance was to allow American and JetBlue to coordinate schedules and pool revenue on flights out of New York and Boston. The first ruling was made by U.S. District Judge Leo Sorokin. A lawsuit was brought by the Department of Justice and six state to block the alliance.

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