On Thursday (October 24, 2025), American Airlines announced the appointment of Nathaniel (Nat) Pieper as Chief Commercial Officer. Currently serving as CEO of the oneworld alliance, Mr. Pieper will assume his new role effective November 3, 2025, reporting to American’s CEO Robert Isom.

In Thursday’s announcement, American Airlines’ CEO, Robert Isom, said,
“Nat is a world-class, results-oriented leader who has achieved tremendous success throughout his entire career. He is well-versed in the airline business, having led teams across multiple disciplines at Northwest, Delta and Alaska. Nat’s experience and expertise, coupled with his recent work with us leading oneworld, make him incredibly well-suited to lead our Commercial team moving forward.”
Nat Pieper joins American after serving as oneworld CEO since April 2024. While at oneworld, he integrated two new airlines into the alliance, launched sustainability and customer experience initiatives, and solidified relationships among member airlines. Pieper’s tenure centered on redefining oneworld’s mission and strategy to focus on premium guest experience, digital integration, initiatives of scale, and implementing a durable and well-defined organizational structure that sets up the alliance for long-term success.
Before joining oneworld, Mr. Pieper spent more than 25 years in commercial and finance roles with Alaska Air Group, Delta Air Lines and Northwest Airlines.
