Violations occurring over a 4½ year period—from October 1993 to July 1998—targeted American Airlines for using high-sulfur fuel in motor vehicles at 10 major airports around the country. Under the federal Clean Air Act high sulfur fuel cannot be used in motor vehicles. American Airlines promptly identified and corrected these violations of the Clean Air Act.
Founded in 1931 as American Airways, American Airlines (AA) is the world's largest airline when measured by revenue and fleet size. A founding member of the Oneworld alliance, AA operates a primary hub at Dallas Fort Worth International Airport (DFW) and has eight secondary hubs at airports across the United States. The airline flies to about 345 destinations in North America, the Caribbean, South America, Asia and Europe. It has codeshare agreements with 15 other carriers, as well as joint ventures with British Airways, Japan Airlines, Iberia, Finnair and Qantas on certain routes. Its fleet consists of 963 aircraft.
In 2011, due to a downturn in the airline industry, American Airlines' parent company AMR Corporation filed for bankruptcy protection. In 2013, American Airlines merged with US Airways but kept the American Airlines name, as it was the better recognized brand internationally; the combination of the two airlines resulted in the creation of the largest airline in the United States, and ultimately the world.
Designers were also excited about the system. It enables product reviews to focus on the actual concepts and experiences of a design, rather than padding, colors and type choices. The DLS provides us with a shared understanding of our visual style, and streamlines contributions to a single system. This system also enables all of us to prototype and experiment with ideas in high fidelity faster and at a lower cost.
