WOOD DALE, Ill., Jan. 28, 2026 /PRNewswire/ -- AAR CORP. (NYSE:AIR), a leading provider of aviation services to commercial and government operators, MROs, and OEMs, has substantially completed the expansion of its Airframe MRO facility in Oklahoma City.

"We are very grateful for Alaska's trust and for the outstanding support we have received in Oklahoma City," said Holmes

Driven by an increased demand for AAR's MRO services, the 80,000+ square foot facility expansion includes three maintenance bays capable of accommodating all 737 variants. The Company will soon induct additional Alaska Airlines aircraft for service as part of a long-term customer commitment.

Earlier today, AAR hosted a ribbon cutting ceremony celebrating the project's near completion, the creation of 200 additional full-time careers with AAR, and the upcoming digitization of the Company's maintenance processes in Oklahoma City in collaboration with Alaska Airlines.

"Today, we celebrate AAR's growth and our longstanding relationship with Alaska Airlines. We are very grateful for Alaska's trust and for the outstanding support we have received in Oklahoma City. We are excited for this new chapter and our decades long relationship," said John M. Holmes, AAR's Chairman, President and CEO.

The Company's maintenance operations in Oklahoma City date back more than 50 years, with AAR's facility located on the site of Will Rogers International Airport's original Hangar 2.
