United Airlines, commonly referred to as United, is a major American airline. It was founded in Boise, Idaho in 1926 and it is currently the second largest airline in the United States to date. It is headquartered in Chicago, Illinois. On May 3, 2010, it was announced that Continental Airlines would merge with United to become one company. The new airlines will take the United name but use Continental's globe identity and livery. There was a lot of negative reaction to the new livery. Most people were in favor of the iconic "Tulip" logo, designed by Saul Bass in 1973.
