On July 3, 2013, the Department of Transportation (DOT) issued an order dismissing all claims remaining in a longstanding dispute involving fees imposed by regulation at Los Angeles International Airport (LAX). Several airlines operating at LAX initially challenged the fees in an administrative proceeding filed in 2007. Both DOT and the U.S. Court of Appeals found fault with certain aspects of how LAWA had calculated the fees, and the matter had been remanded to DOT for further consideration. LAWA ultimately negotiated agreements with the airlines over fees, in which the parties also agreed that the claims challenging the prior fees were moot. Upon motions of the parties, DOT dismissed the claims of the airlines with prejudice and terminated the proceeded.
