Exhibit 99.3

Date: Aug. 4, 2010

Subject: Atlantic Southeast reaches definitive agreement to acquire ExpressJet Holdings, Inc.

Over the past couple of years we have talked a lot about the importance of staying focused on delivering a safe, high-quality and reliable product for our customers and business partners in order to position our airline well for new opportunities. Because of your hard work and commitment to upholding our high standards, we are now in a position to take advantage of one of those opportunities.

SkyWest, Inc. this morning announced that Atlantic Southeast has entered into a definitive merger agreement to acquire all outstanding common stock of ExpressJet Holdings, Inc., parent company of ExpressJet Airlines. This announcement is a significant step in our company’s evolution and reflects the agreement of the SkyWest and ExpressJet boards of directors to enter into this transaction. If the ExpressJet shareholders approve the proposed transaction, the parties are successful in obtaining all required regulatory approvals, other customary conditions are satisfied and the proposed transaction is completed, we plan to immediately begin the process of integrating the airlines, with the objective of operating a single, efficient regional airline.

Before I share some of the details, I cannot stress enough how important it is that people in every division, in every position, maintain focus on our operational performance goals of on-time, completion, D-0 and customer satisfaction, with safety remaining at the core of everything we do. The transition process should be invisible to our customers and business partners, and I ask that you continue providing our passengers the high-quality service they have come to expect.

Initially, we intend to maintain the separate operating certificates of both airlines, and ExpressJet will retain everyday operational control and decision-making of its airline until the proposed transaction is completed and the necessary regulatory approvals are issued. We expect the legal transaction to be completed during the fourth quarter of 2010, and we propose to work over the 12 to 15 months following completion of the transaction to combine the operations of both airlines and obtain a single operating certificate. Many decisions will need to be made regarding the proposed integration, and we are in the process of identifying post-merger integration (PMI) teams for every division, with the goal of including employees from both airlines on each team, to the extent permitted by applicable laws and regulations.

We believe the integration of ExpressJet into Atlantic Southeast will create significant cost efficiencies that will give the combined airline the financial strength to be a strong competitor for new business and existing contracts. We also believe employees will benefit from improved long-term career opportunities and enhanced job stability by being part of a larger, financially stronger and more geographically diverse airline that is better able to compete successfully in the highly competitive regional marketplace.

This transaction does not impact Atlantic Southeast’s existing contracts, but it does include a new long-term, 10-year Capacity Purchase Agreement for ExpressJet with Continental Airlines, which would be effective once the legal acquisition is complete and will be transferable in integration. If executed, it would among other provisions, provide a replacement option whereby Atlantic Southeast would be awarded larger aircraft (subject to then-existing scope clause limitations) if Continental decides to pull any of the existing 50-seat aircraft flown by ExpressJet.

For the employees of Atlantic Southeast Airlines, Inc.

I expect this news will spur many questions. We have developed a dedicated “Taking Flight Together” page on ourASA where we will house employee-focused information about the proposed transaction. It includes an employee FAQ, an officer roadshow schedule and other tools and information that employees should find useful. Additional information about the proposed transaction is also available through the SkyWest, Inc. website (www.skywest.com) and in SkyWest, Inc.’s filings with the U.S. Securities and Exchange Commission.

As always, I am committed to keeping Atlantic Southeast people up to date as material developments occur with respect to the proposed transaction. As we pursue the required regulatory approvals and ExpressJet works to obtain the approval of its stockholders, I intend to provide additional information as it becomes available. Again, during this transition it is essential that we maintain focus on operating our airline safely and efficiently, as we continue providing a quality product for our customers and business partners, alike.

The diligent efforts of Atlantic Southeast people in every division have helped position us well to capitalize on new opportunities, including the proposed ExpressJet transaction. I want each of you to know that I appreciate your hard work to position us so that we are able to entertain this transaction and take one step closer to becoming the world’s first super regional carrier.

Thank you for what you do every day to make Atlantic Southeast a leader in the regional airline industry and a great team to be a part of.
