6 Key Items to Watch in the US Airways/AMR Merger

"Right now, I would imagine most American Airlines employees are open-minded and excited about a new management team and see Doug Parker and his crew as sort of white knights," said James Ray, spokesman for the US Airline Pilots Association. "So this is a time when Mr. Parker's leadership team should go out of its way to ensure it take cares of employees and motivate employees, because ultimately, it is the employees who can assure that this airline succeeds."

Parker's engaging personality led to an internal communications strategy that frequently places him in employee meetings. The strategy worked for America West but was probably taxed a bit when the airline expanded. Can it still work at the largest airline in the world?

Hub Utilization

For airline geeks, this could be the most fascinating part of the merger. US Airways has hubs in Charlotte, Philadelphia and Phoenix and dominates Washington Reagan National Airport. American has hubs in Chicago, Dallas, Miami, Los Angeles and New York. US Airways has benefited immensely from a strategy of focusing 99% of flying in the four cities it dominates, while American has suffered from trying to build hubs at airports it doesn't dominate.

What will US Airways do now? Charlotte, Dallas and Philadelphia seem likely to grow, while Miami seems unlikely to diminish. Over time, Phoenix seems destined to lose some connecting east-west flights to Dallas. After all, does Fresno require five daily flights to Phoenix plus two to Dallas? What changes in Chicago, where American is No. 2 to United? And how will a major hub in Philadelphia interact with a small hub at Kennedy?

Alliance Politics

US Airways has already said it will leave Star Alliance for Oneworld, assuring continuation of a rational setup combining three major U.S. airlines with three global alliances.

Given that American has a limited presence in Asia and US Airways has none, Oneworld partners Japan Air Lines and Cathay Pacific will be heavily involved in getting American passengers to Asia. "They have to quickly wrestle with the question of how to fill the gap in Asia, and they have to come to an early and robust decision on how to fill that gap," said aviation consultant Robert Mann. Oneworld doesn't include a mainline China airline.

Of course, it is easy to say you will leave Star, but somewhat tougher to actually do so. "These divorces are expensive 12-month exercises," Mann said. "You have to manage the divorce and then get married to someone else, but in this case you want to get married before you get divorced."

Other questions will involve international partners. For instance, will Oneworld member British Airways return to Charlotte? Will Star member Lufthansa continue to fly Charlotte-Munich?
