SKYWEST COMPLETES EXPRESSJET ACQUISITION

St. George, Utah — SkyWest, Inc. (NASDAQ: SKYW) today announced the completion of its acquisition of ExpressJet Holdings, Inc., the parent company of ExpressJet Airlines, Inc., a regional air carrier which serves more than 130 scheduled destinations in North America and the Caribbean with approximately 1,200 departures per day (“ExpressJet”).  As a result of a merger transaction declared effective earlier today, ExpressJet Holdings, Inc. became a wholly-owned subsidiary of Atlantic Southeast, Airlines, Inc. (“Atlantic Southeast”), which is a wholly-owned subsidiary of SkyWest.

“Our acquisition of ExpressJet represents a significant step in the implementation of our strategic plan” said Bradford R. Rich, SkyWest’s Executive Vice President and Chief Financial Officer.  “We are pleased to welcome ExpressJet’s employees into the SkyWest organization and look forward to capitalizing on the synergies we believe the acquisition presents.”

SkyWest confirmed its intention to combine the operations of ExpressJet and Atlantic Southeast, subject to receipt of necessary regulatory approvals, and utilize Atlantic Southeast’s existing facilities in Atlanta, Georgia as the operating headquarters of the combined company.  SkyWest anticipates that both airlines will continue to operate under separate airline operating certificates until the regulatory process can be completed for combining the airlines under a single operating certificate.  Pending receipt of that single operating certificate, Atlantic Southeast intends to transition certain existing ExpressJet support functions to Atlantic Southeast and SkyWest.  SkyWest believes that ExpressJet employees and passengers will benefit from the merger by building greater efficiencies of scale and capitalizing on

growth opportunities.

“With the completion of the acquisition, Atlantic Southeast and ExpressJet personnel have commenced the process of integrating their respective operations to ensure a smooth transition designed to deliver immediate value for customers and shareholders” said Rich.  “We believe the combined operations of Atlantic Southeast and ExpressJet, together with the operations conducted by SkyWest Airlines, Inc. (“SkyWest Airlines”), position us to offer an exceptional product to our passengers and major partners, provide growth opportunities for our employees and create additional value for our shareholders.”
