AAR CORP. broke ground on the expansion of its maintenance, repair, and overhaul facility in Oklahoma City earlier on April 5, 2024. More than 150 representatives from AAR, Alaska Airlines, state and local government, and partner organizations supporting the efforts gathered to celebrate on AAR's new three-bay facility that is being constructed adjacent to the Company's existing facility at Will Rogers World Airport.

The new facility has been designed to provide AAR an additional 80,000+ square feet of hangar and warehouse space and to accommodate all 737 variants, including the 737-10. AAR's growth in Oklahoma City supports a recently expanded maintenance commitment from Alaska Airlines, a valued customer of AAR for more than 20 years. The new airframe MRO facility is expected to be operational in January of 2026.

Considerable funding for the project was made possible through a grant secured by Oklahoma legislators, with the balance expected to be funded through rent concessions from the airport.
