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". It also marked the return of the full name (albeit with "Airlines" being one word this time).

====1988–1993====
An alternative version of United Airlines' wordmark was introduced in 1988. At the same time, United Airlines and "the tulip" logo designer Saul Bass also modified the aircraft livery, which makes the cheatline across windows to be lowered by one color line (except Boeing 747, which still keeps the 1974 cheatline design) and larger horizontal variant wordmark at front of fuselage.

In January 1993, the United tulip and brand were refreshed by CKS Partners. This logo appeared on airplanes painted in the "Battleship Grey" livery from 1993 to 2004, and was commonly seen until 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 remained 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.

On August 11, 2010, the initial merger identity was replaced after only four months, with a tweaked logo and livery revealed. The merger was officially completed on October 1, 2010.
