Today marks an important step in the evolution of our airline, reaching agreement to merge with US Airways, combining the best of both carriers to create a leading global airline that provides superior value to our customers, partners and people. As Tom shared, this significant opportunity was made possible through the hard work and dedication demonstrated by each of you through the past year, and the value you created in our airline.

In his Special Jetwire, Tom discusses how the improvements we realized through restructuring—including a transformed fleet with hundreds of planes on order, an improved revenue performance, enhanced products and services and the reveal of our new look—positioned us to make a deal that will help put American back on top. With a solid financial foundation, unmatched network scale and the best team in the industry, the new American will be second to none.

Tom also shared his sentiments in a video to employees, where he reflected on all the reasons American’s people have to be proud of our impressive progress through the past year. He emphasized that this merger will move us closer to our goal of providing superior customer service, and a modern, comfortable travel experience for all passengers, and noted that becoming a stronger, more competitive airline will lead to better opportunities and benefits for all of us. Watch Tom’s thank you to the American team in the full video, housed on the new Jetnet Merger space.

AMR in the News

From The New York Times American and US Airways Announce Deal for $11 Billion Merger

Ending a yearlong courtship by US Airways, American Airlines agreed to merge with the smaller carrier, paving the way for the creation of the nation’s largest airline. A merger would bolster American’s domestic footprint, strengthen its presence in the Northeast and give it a bigger network to attract business travelers and corporate accounts. The merger would create a company with the size and breadth to compete against United Airlines and Delta Air Lines, which have grown through mergers of their own in recent years and are currently the biggest domestic carriers. The combined airline will have more than 100 million frequent

fliers. The wave of big mergers in the industry has created healthier and more profitable airlines that are now better able to invest in new planes and products, including Wi-Fi, individual entertainment screens and more comfortable seats for business customers.

The deal, which was completed in recent days, could be formalized as American leaves bankruptcy. Doug Parker said that the two airlines have only 12 routes overlapping out of a combined 900 routes that the two airlines serve together. In addition, he said, more cities would be serviced: American flies to 130 cities that US Airways does not fly, and, likewise, US Airways flies to 62 cities that are not served by American. In this case, the merged American Airlines will still be based in Fort Worth and have a combined 94,000 employees, 950 planes, 6,500 daily flights, eight major hubs and total revenue of nearly $39 billion. It would be the market leader on the East Coast, the Southwest and South America.
