Two provisions of the Railway Labor Act do not create a private right of action for flight attendants to challenge the reworking of their labor agreement to avoid an American Airlines bankruptcy, a federal appeals court ruled Tuesday.

Addressing a case of first impression, the 2nd U.S. Circuit Court of Appeals said the first and seventh provisions of the act, 45 U.S.C. §152, do not empower individual flight attendants to challenge the validity of a Restructuring Participation Agreement reached between their union, American Airlines and its parent company AMR Corp. in 2003.
