Major Airlines Sued for Allegedly Using Shared Fare System to Fix Ticket Prices

Five major US airlines (American Airlines, Delta, Southwest, Alaska Air, JetBlue) and ATPCO face a federal lawsuit alleging they used a shared fare system to monitor and coordinate ticket prices, violating antitrust laws. The complaint claims this practice artificially inflated air travel costs. ATPCO, an airline-owned fare database, is central to the case. The lawsuit echoes a 1992 DOJ case that resulted in consent decrees, raising questions about the effectiveness of those measures.
