American Airlines Appoints Oneworld CEO Nathaniel Pieper Chief Commercial Officer

American Airlines has appointed Nathaniel Pieper, current CEO of the Oneworld airline alliance, as its new Chief Commercial Officer effective November 3, 2025. Pieper brings over 25 years of experience from leadership roles at Northwest Airlines, Delta Air Lines, and Alaska Airlines, where he notably led Alaska's entry into Oneworld and fostered partnerships with American. His appointment follows the departure of former CCO Vasu Raja after a failed business travel strategy that alienated corporate customers and hurt revenue. American's CEO, Robert Isom, praised Pieper as a collaborative, results-driven leader with deep airline industry expertise who will lead commercial strategy, loyalty programs, network planning, and sales departments. Vice Chairman Steve Johnson, who had been overseeing the commercial organization since Raja's exit, will return to his role as Chief Strategy Officer. American Airlines aims to recover and grow its corporate revenue and market share, emphasizing loyalty program growth and commercial stability under Pieper's leadership.
