A Message from Chairman and CEO Tom Horton

Dear American Team:

We are now in the home stretch of our restructuring, and thanks to the hard work of our entire team, these results are remarkable. Today we filed our Monthly Operating Report for April which highlights our financial progress. I’m pleased to report that, excluding reorganization and special items, we posted a very strong improvement to our bottom line. And if current trends continue, we are well on our way to a strongly profitable second quarter.

In addition to improving our financial performance, we are picking up the pace on the renewal of almost every facet of our company. This means investing in a new and modern fleet. In addition to the steady stream of new 777-300s, we’ll soon introduce the first Airbus A319s and A321s into our fleet. In total we’ll add 59 new aircraft this year. It also means new service to new markets across the globe like Seoul and Düsseldorf. And of course, it means refreshing the customer experience with enhancements like the new Flagship check-in at JFK, and new technology to help you serve our customers.

And at the start of another busy summer travel season, our operation is running well. From January through April, you have achieved an on-time arrival rate of over 78 percent. And our completion factor for the same period was 98.3 percent, which is the best performance in seven years.

All of this is building great momentum heading into our merger with US Airways to create the world’s leading airline. The transformation of American is a direct result of your hard work and unwavering focus on our customers every day. You are putting American back on top.

Thanks for all you do.

Tom
