American Airlines petitions US Supreme Court on Northeast Alliance

American Airlines is asking the U.S. Supreme Court to review a lower court’s decision that spelled the end of its Northeast Alliance with JetBlue.

In a petition filed to the high court, the Fort Worth, Texas-based carrier called a nearly two-year-old ruling against the joint venture between the two airlines a “clear legal error” and one that “threatens to wreak havoc” on future collaborations between other companies.
