Stockholders Approve United Continental Merger

Dear fellow employee,

Today our shareholders overwhelmingly approved our proposed merger with Continental, effectively clearing our path for closing by Oct. 1.

This is great news for our people, our customers, and our stockholders and provides United with the opportunity to again be the world’s leading airline. With this merger, we have the best people and the world’s best network, providing service to 350 destinations and connections to 1,000 destinations through our Star Alliance partnerships.

For our customers and for our people, changes will be apparent over time as we build upon the integration planning work our two companies have been engaged in for the past five months and begin to fully integrate. That’s really what this merger is all about: bringing together the best of two great airlines, resulting in a company that will be well positioned to provide stability and career advancement for our people.

The path leading to this merger has not been an easy one for our industry, our company, our people or our shareholders. Together, we have weathered skyrocketing oil prices, natural disasters and a devastating recession.  During these tumultuous years we have restructured our company, taking it from bankruptcy to industry-leading on several financial and operating metrics -- and now we are back as a global leader.

Through it all, we focused on doing the work and making the right decisions to ensure United would be well positioned to succeed.

Closing our merger is a significant step on a longer path – and now that journey continues, as our two companies can begin to work together to create the world’s leading airline for our customers, our people and our shareholders.

We are in the position we are today because of all the great work happening all across the company, and I would like to thank our board of directors and all of you for your part in creating the new United Airlines.

Glenn
