Corporate identity


Brand image

The pre-merger United logo, commonly nicknamed the "tulip", was developed in the early 1970s by the designer
Saul Bass Saul Bass (; May 8, 1920 – April 25, 1996) was an American graphic designer and Oscar-winning filmmaker, best known for his design of motion-picture title sequences, film posters, and corporate logos. During his 40-year career, Bass wor ...
as part of a new brand image. The logo represented the airline's monogram as well as a modernized version of the airline's shield logo which had been adopted in the 1930s, but fell out of use by the late 1960s. The ribbon-like rendering has also been said to symbolize the motion of flight.


Marketing themes

United's earliest slogan, "The Main Line Airway", emphasized its signature New York-Chicago-San Francisco route, and was replaced in 1965 with "Fly the Friendly Skies", which was in use until 1996 in its first iteration. The "It's time to fly" slogan was created in 2004. After the merger of United and Continental in October 2010, the slogan changed to "Let's fly together" until September 2013, when United announced a return of the "Fly the Friendly Skies" slogan in an ad campaign to start the following day. The resurrected slogan would be accompanied by the 1924

and Boeing, announced that United had agreed to replace the Blended Winglets on its Boeing Next Generation 737 aircraft with APB's Split Scimitar Winglet (SSW), significantly reducing drag. Once the SSWs are installed, it is estimated that APB's winglet technology will save United more than $250 million annually in fuel costs. On June 30, 2015, United invested US$30 million in Fulcrum BioEnergy, an alternative fuel company. Fulcrum's alternative fuel is produced through a clean and efficient thermochemical process and reduces lifecycle carbon emissions by more than 80 percent. As part of its investment, United will work with Fulcrum to develop up to five alternative fuel refineries near its U.S. hubs. These refineries will produce up to of sustainable aviation alternative fuel per year, and United will have the opportunity to purchase at least per year for a minimum of 10 years, making it the largest aviation alternative fuel commitment to date. On March 11, 2016, United became the first airline in the world to fly on commercial-scale quantities of such fuels on a continuous basis, which were procured from AltAir Fuels. This fuel was produced from sustainable feedstocks such as non-edible natural oils and agricultural wastes and is expected to provide a greater than 60 percent reduction in carbon dioxide emissions on a lifecycle basis when compared to traditional jet fuel. United has agreed to purchase up to of sustainable alternative fuel from AltAir Fuels for use in

. A new Joint Collective Bargaining Agreement was ratified by a majority of the United/Continental pilots on December 15, 2012, which struck down a scope clause that disallowed Continental from outsourcing the flying of regional jets with 70 or more passenger seats. In January 2021, as a plan to reduce its costs in 2023, United Airlines offered its employees voluntary leave options with pay or health benefits. In April 2021, United Airlines announced that within the next decade, half its pilot cadets in the United Aviate Academy would be female or people of color.


Concerns and conflicts


Animal transport

In 2013, after pressure from PETA, United announced that it would no longer transport monkeys to laboratories. United was the last North American passenger airline to transport these animals to laboratories. United flies more animals and has longer flight stage length than any other US airline, and accounted for one third of animal deaths of US airlines between 2012 and 2017. Effective March 20, 2018, the PetSafe program was suspended with no new reservations for cargo transport of pets accepted. This came after United announced plans to mark pet carriers in the passenger cabin with bright tags and legislation was introduced in the United States House of Representatives and United States Senate banning the placement of pets in overhead compartments. This was in response to a dog death after a passenger placed it in the overhead compartment following flight attendant instructions, but the flight attendant denied knowing that the luggage contained a dog.


Cyber security issues

United awarded airline miles as " bug bounties" to hackers who could identify gaps in the carrier's web security. Two hackers have each been rewarded with 1 million miles of air travel as of July 15, 2015. This cybersecurity program was announced a few weeks after the company experienced two software glitches. The first incident delayed 150 United flights on June 2 due to a problem with its flight dispatching system. Six days later, United's reservation system delayed flights by not allowing passengers to check-in. In addition to the "bug bounty" program, United said it tests systems internally and engages cybersecurity firms.


Privacy concerns

In February 2019, privacy concerns arose after it emerged that United had installed cameras in some seat backs. United said that the cameras were "not activated", but journalists reported that malicious hackers could still potentially enable the cameras to spy on passengers.


Mail-scan fraud

In February 2021, United Airlines was fined $49 million by the Department of Justice on charges of fraud on postal service contracts for transportation of international mail. According to investigators, between 2012 and 2015 United submitted delivery scan data to make it appear that United and its partner airlines complied with International Commercial Air requirements with accurate delivery times when in fact they were automated delivery scans with aspirational delivery time. Some employees within United worked to hide this fact from the USPS.

. United announced that it needed four seats for airline staff on the sold-out flight. When no passengers volunteered after being offered vouchers worth $800, United staff selected four passengers to leave. Three of them did so, but the fourth, a doctor named David Dao, declined as he said that he had patients to treat the following morning. He was pulled from his seat by Chicago Department of Aviation security officers and dragged by his arms down the aisle. Dao sustained a concussion, broken teeth and a broken nose among other injuries. The incident was captured on smartphone cameras and posted on social media, triggering angry public backlash. Afterwards, United's then-chief executive officer, Oscar Munoz, described Dao as "disruptive and belligerent", apologized for "re-accommodating" the paying customers, and defended and praised staff for "following established procedures". He was widely criticized as "tone-deaf". Munoz later issued a second statement calling what happened a "truly horrific event" and accepting "full responsibility" for it. After a lawsuit, Dao reached an undisclosed settlement with United and airport police. In the aftermath, United's board of directors decided that Munoz would not become its chairman and that executive compensation would be tied to customer satisfaction. Following this incident, passenger complaints increased by 70 percent.
