AAR, a leading global provider of aviation services, has substantially completed a major expansion of its Airframe Maintenance, Repair and Overhaul (MRO) facility in Oklahoma City. The more than 80,000-square-foot expansion adds three new maintenance bays capable of accommodating all variants of the Boeing 737, driven by growing demand for AAR's MRO capabilities. AAR hosted a ribbon-cutting ceremony to celebrate the expansion, the creation of approximately 200 new full-time jobs, and the forthcoming digitization of maintenance operations at the site in collaboration with Alaska Airlines.

Why it matters

The expanded Oklahoma City facility further strengthens AAR's Airframe MRO offerings, supporting the company's continued growth and commitment to operational excellence. The expansion also underscores AAR's long-standing presence in the region, with maintenance operations in Oklahoma City spanning more than 50 years.

The details

The expansion was driven by growing demand for AAR's MRO capabilities and adds three new maintenance bays, each capable of accommodating all variants of the Boeing 737. As part of a long-term customer commitment, AAR will soon induct additional Alaska Airlines aircraft at the facility. The digital transformation at the site will be carried out in collaboration with Alaska Airlines.
