AAR and Allegiant Commemorate 100th Aircraft Delivery

Leading aircraft maintenance provider and long-term customer celebrate milestone

OKLAHOMA CITY, Oklahoma – AAR (NYSE: AIR) and Allegiant Air, joined together in a hangar at AAR’s aircraft maintenance facility in Oklahoma City to celebrate the delivery of the 100th airplane as part of their long-term aircraft maintenance relationship.

In 2008, AAR signed an agreement with Allegiant to provide aircraft Maintenance, Repair and Overhaul (MRO) services from its Miami based aircraft maintenance facility. Subsequently, additional work was performed at AAR’s MRO facility in Oklahoma City and, in 2010; AAR and Allegiant inked a five-year agreement for AAR to serve as the exclusive aircraft maintenance provider for Allegiant’s MD-80 fleet. Today, through its North American “1MRO” network, AAR provides Allegiant with aircraft maintenance and modifications from full-service facilities in Oklahoma City, Miami and Indianapolis.

“We value our excellent relationship with Allegiant and are proud to celebrate this momentous occasion with the Allegiant and AAR teams who worked to achieve this important milestone,” said Dany Kleiman, Group Vice President for AAR’s MRO operations. “While today is about celebrating what we’ve accomplished, we’re looking toward the future with an enduring commitment to providing high levels of service to help Allegiant operate its fleet safely and efficiently while maintaining their high levels of passenger service.”

AAR offers customers turnkey aircraft support solutions as part of its “1MRO” approach. The Company leverages diverse maintenance, engineering and technical capabilities to offer airlines customized, integrated services that lower costs, increase asset availability and ensure high levels of quality, safety and service. In addition to its facilities in Oklahoma City, Miami, Indianapolis, and Hot Springs, Arkansas, AAR is in the process of standing up a fifth MRO facility in Duluth, Minnesota, expected to open this year.

Earlier this year, AAR was voted by customers as Best Airframe MRO Provider — The Americas. AAR is also ranked the No. 5 MRO in the world and was also named Aircraft Parts Supplier of the Year in an independent survey of 11,000 airline executives and industry professionals.
