CO/UA Merger: What Happens Next?

I’ve enjoyed meeting with several thousand of you since we announced our plan to merge with United. I’ve gotten a lot of questions, and we are doing our best to get answers to you in a timely manner. One thing that just about all of you want to know about is “what happens next?”

The next step is that Glenn Tilton and I will lead a merger integration planning team that will review information and make decisions about how to best combine the two airlines. This team will function between now and the closing of the merger, which we expect to occur later this year. The employee bulletin [LINK] we put out on this topic today explains more about the structure we’ll use for this planning process.

While many co-workers will be asked to contribute to the integration planning process, you shouldn’t be concerned if you aren’t directly involved. We still need to run an outstanding airline, and that job is vitally important. Some of our integration planning teams, such as those tasked with figuring out pass travel and uniforms, will reach out for co-worker input, and we will communicate how you can help out later. We intend to make this process collaborative and to access the wisdom and experience of many of our co-workers.

Looking ahead, after the legal merger, we will begin the important process of integrating the two carriers into a single operating entity. This process, which is known as the operational merger, should be complete by the first half of 2012. Some of the major milestones that will happen between now and when we start operating as a single airline are shown on the timeline below.

The following employee bulletin was first distributed to employees on May 19, 2010:

EMPLOYEE BULLETIN NO. 11

CO AND UA ESTABLISH STRUCTURE FOR MERGER INTEGRATION PLANNING

     CO and UA have agreed on the structure and named the leadership for the merger integration planning team, which will oversee the integration planning process. The integration planning process will last through the closing of the merger, which is expected to occur later this year. Following the closing of the merger, the important integration implementation process will begin, as we work together to combine the two carriers into a single operating entity.

     A six-member steering committee will oversee the process and make key decisions. The members of the steering committee from CO are Jeff, EVP and CFO Zane Rowe and EVP and Chief Marketing Officer Jim Compton, and the members from UA are Glenn Tilton, EVP and CFO Kathryn Mikells, and EVP and Chief Administrative Officer Pete McDonald. Pete McDonald and Lori Gobillot, CO’s staff VP and assistant general counsel, will oversee the integration management office (or IMO), which will develop and manage the integration process and report to the steering committee. Under the IMO, there will be five major groups representing broad functional areas of the business (commercial, operations, corporate and other, IT & systems integration and single operating certificate planning), each led by a CO representative and a UA representative, with numerous functional subgroups under each major group. It will take some time to form and begin to manage the teams that will participate in each subgroup.

     Now that the structure is in place, it will take some time to develop the detailed process and commence the integration planning work. Once the functional group teams begin their work, we will communicate about ways that co-workers can provide meaningful input to those teams.

     “The merger integration planning will require a detailed and very organized examination of how our businesses will best fit together,” Jeff said. “Now that we have a planning structure in place, we will begin to work together with our colleagues from United to review the many issues and make the planning decisions that will help us create the world’s leading airline. This will be a long and complex process, with many of our and United’s co-workers dedicating substantial time to it. We will keep you informed as we move forward.”
