Airlines, ATPCO Prevail In Agent-Led Appeal Of 'Sum-Of-Sector' Suit

A three-judge panel from the U.S. Court of Appeals for the Ninth Circuit last week affirmed a lower court ruling that favored airlines in a travel agent-led lawsuit related to "sum of sector" fare rules. Filed in 2016, agent plaintiffs had alleged American, Delta and United, aided by ATPCO, conspired to change fare combinability rules that raised the cost of some multi-city tickets in 2016.
