This logo was introduced in the early 1940s. It was a simplification of an earlier shield logo first introduced in 1936.
Around the early 1950s, the shield logo was altered with a slight slant added.
Another change to the logo came around the early 1960, when United merged with Capital Airlines. The word "United" was made bigger and the rest of the name disappeared from the icon.
An oblique vertical "spike," blue on bottom and red on top, running through the name "United" written in a black or blue serif italic font.

In September 1974, United introduced a new logo designed by famed logo creator Saul Bass. The logo features a stylized "U" slanted 68 degrees. It sometimes goes by the nickname; "the tulip".
In 1993, the United tulip and brand was refreshed by CKS Partners. This logo appeared on airplanes painted in the "Battleship Grey" from 1993 to 2004 and was common into 2011.
In 1998, United started implementing a new identity created by Pentagram. This logo was featured on airplanes in the new "Rising Blue" livery, However, this would not show up on aircraft until early 2004
In 2010, United acquired Continental Airlines in a merger completed later that year. Initially, the entities remain separate, with United continuing to use a variant of the slant U logo. The logo and livery was presented with the merger on May 3 and keeps most aspects of Continental's identity, but replaces the Continental name with United.
The initial merger identity was replaced after only three months. On August 11, 2010, a tweaked logo and livery was revealed. The merger was officially completed on October 1, 2010.
