March 3 (Reuters) - American Airlines ( AAL ) has asked

the U.S. Supreme Court to reverse a lower-court decision that

found its now-scrapped U.S. Northeast partnership with JetBlue

Airways ( JBLU ) violated federal antitrust law.

American Airlines ( AAL ) in a petition made public on Monday asked

the justices to review a decision in November by a Boston-based

federal appeals court that upheld a trial judge's ruling

blocking the airlines' "Northeast Alliance," which had allowed

the two carriers to coordinate flights and pool revenue.
