United Airlines is a major airline headquartered in Chicago, Illinois. It is considered the world's largest airline in terms of passenger miles flown. The United "U" logo, pictured on this button, is known as the "tulip". It was developed in the early seventies and was used in different variations up until 2012. The logo was changed to a blue globe after United merged with Continental airlines. The post-merger logo change was heavily criticized by marketing experts and designers, who state that it has weaker brand recognition than the "tulip" logo.
