The following articles will be included in the CO Times company publication that will first be made available to employees on July 1, 2010:

Jeff testifies before House and Senate regarding merger

     For several days last month, Jeff and United CEO Glenn Tilton testified before House and Senate panels reviewing the pending merger. Jeff and Glenn read opening statements and answered questions at each hearing, which also included the testimony of other witnesses, including union spokespeople, industry analysts, consumer groups and Department of Transportation (DOT) representatives.

     Jeff and Glenn spoke before the U.S. House Committee on Transportation and Infrastructure’s Subcommittee on Aviation, the U.S. House Committee on the Judiciary and the U.S. Senate Committee on Commerce, Science and Transportation.

     “I would like to make four main points: this merger is good for employees; is good for communities; is good for consumers; and is good for competition,” Jeff said in his opening remarks.

Good for employees

     “After we merge, our employees will be part of a larger, financially stronger and more geographically diverse carrier,” Jeff said. “This carrier will be better able to compete in the global marketplace and better able to withstand the external shocks that hit our industry with disappointing regularity.”

     Jeff reiterated that because of how little CO’s and UA’s routes overlap, “the merger will have minimal effect on the jobs of our frontline employees. We are committed to continuing our cooperative labor relations and to integrating our workforces in a fair and equitable manner and negotiating contracts with our unions that are fair to our employees and fair to the company,” Jeff said.

Good for communities

     Jeff said that following the merger, the company plans “to continue to provide service to all of the communities we currently serve, including 148 small communities.”

Good for customers

     “The combined airline will offer consumers an unparalleled integrated global network and the industry’s leading frequent flyer program,” Jeff noted, adding that the company “will have the financial wherewithal to invest in technology, acquire new aircraft and invest in its people and its product.”

Good for competition

     Jeff pointed out that the CO and UA networks “are so complementary that we have only minimal nonstop overlaps, each of which faces significant competition after the merger.” Foreign carriers that have created global networks in recent years will still pose significant competition for the business traveler and low-cost carriers will continue to compete at domestic hubs and regional airports.

Better positioned

     “In sum, the merger will create a strong, financially viable airline that can offer good-paying careers and secure retirement to our co-workers, great customer service and an unparalleled network to consumers, and reliable service to communities,” Jeff said. “The merger will provide us with a platform

for sustainable profitability and position us to succeed in the highly competitive domestic and global aviation industry — better positioned than either airline could be alone or together in an alliance.”

» Operations Update with Mark Moran

     Merging any two large companies is a complex task. When those two companies are airlines, the job involves thousands of details. While we expect legal approval of our merger with United Airlines (UA) by year end, it’s not the legal approval that will allow us to actually operate as a single carrier. In order to operate as one airline, we need to get our single operating certificate (SOC) from the Federal Aviation Administration (FAA). Until that time, CO and UA will need to continue to operate as two separate carriers. Our pilots will fly only on CO aircraft. Our technicians will only work on CO aircraft doing work with our own manual. We will continue reporting separate monthly Department of Transportation (DOT) statistics.

     The FAA provides the guidelines or steps required to apply for an SOC when companies merge. We hope to submit a transition plan for the SOC this fall. This plan will identify the FAA principal base of operations, and document efforts to ensure that a high level of safety continues at both carriers. The transition plan includes how the company will integrate training programs, manuals, maintenance programs and operating procedures.

     This process will take some time. CO has more than 400,000 pages of manuals that must be reviewed. For example, we have a deicing manual of approved deicing procedures. UA has a deicing manual of its own. The two manuals will have to be combined into one, and co-workers will need to be trained on the new process. Then the FAA must approve the new manual.

     One of our focus items as we work through this integration process is safety. We are going to document the safety systems using the FAA’s Air Transportation Oversight System (ATOS) and combine our two safety programs into one.

     Safety Staff VP Don Gunther and Mike Quiello, UA’s VP of Corporate Safety and Security, Quality and Environment, have been assigned to work on the planning for the SOC. Other co-workers, such as Technical Services VP Ken Burtt and Jim Starley from Flight Operations will put in a significant amount of time getting us prepared.

     The first kickoff meeting is July 9 with the FAA in Washington. CAVOK, a division of Oliver Wyman, Inc., our SOC consultants, will help provide the tools and project management support.

     While all this is going on, we remain CO and we will operate as CO.

     After that, the FAA will review the transition plan.

     Then in Phase Three, after the plan is reviewed and accepted by the FAA, inspectors will closely monitor the implementation process. The final step is when the FAA approves and issues the SOC. This is expected to occur in the first half of 2012.

     Although this is a long and detailed process, I’m confident that our team will work diligently through every step necessary to make operating as a single carrier a reality. I’ll report back to you on our progress in a few months.

Jeff’s Letter

Dear co-worker:

     Since our announcement in May that we’ll join with United in a merger of equals, we’ve been hard at work laying the groundwork for the new airline. We’re working quickly, but also carefully, because we are at a major turning point in our airline’s history. We have the opportunity of a lifetime to create the world’s greatest airline, and to do so, we’ve got to take a good look at all of the fundamentals that make an airline succeed or fail. At Continental, by far the most important fundamental — and the most important ingredient in our success — has been our culture.

     Fifteen years ago, we were also at a turning point. Gordon brought me to Continental in 1995 as part of the management team tasked with turning the airline around, and I remember what it was like. Many of you were here then, and I bet you remember this as well: We had great people who wanted to do a great job, and we had strong assets like our hub structure. What we didn’t have, and what we put into place, was a good culture.

     So what is culture? If you ask 10 people, you’re likely to get 10 different answers. What I’ve seen at Continental is that culture is about principles: principles like Working Together toward shared goals that everybody knows. Principles like direct, open and honest communication. Principles like treating co-workers and customers with dignity and respect. Principles like empowering employees to make decisions and giving them the tools they need to succeed. We implemented these concepts back in the 1990s, and they allowed our people to really shine. You provided our customers with great service, and the awards and accolades began to roll in.

     These principles will be the foundation of the new airline, just as they have been our magic for all these years. United’s leadership also recognizes the power of culture, and we will pick a management team for the new airline that mirrors this commitment. The leadership team will help create the conditions for a successful culture, and then it depends on all of us — you, me, and all of the United co-workers — to put our principles into action. Our culture will be successful because of you.

     Both United and Continental have great people. We’re going to let our principles be the guiding force, and together, we’re going to create the greatest airline in the world.

Jeff

• Distributed two Q&As to employees

• Received “Second Request” for information from DOJ, as expected

• Jeff testified at Senate and House hearings
