United Airlines Holdings, Inc. (formerly known as United Continental Holdings, Inc., UAL Corporation, Allegis Corporation and founded originally as UAL, Inc.) is a publicly traded airline holding company headquartered in the Willis Tower in Chicago. UAH owns and operates United Airlines, Inc.
UAL Corporation agreed to change its name to United Continental Holdings in 2010, when an agreement was reached between United and Continental Airlines where the two airlines merged in an $8.5 billion all-stock merger of equals on October 1, 2010. To effect the acquisition, Continental shareholders received 1.05 shares of UAL stock for each Continental share; at the time of closing, it was estimated that United shareholders owned 55% of the merged entity and Continental shareholders owned 45%. The company or its subsidiary airlines also have several other subsidiaries. Once completely combined, United became the world's largest airline, as measured by revenue passenger miles. United is a founding member of the Star Alliance.

On June 27, 2019, the name of the parent company was changed from United Continental Holdings to United Airlines Holdings.

## Development

Early in February 2008, UAL Corporation and Continental Airlines began advanced stages of merger negotiations and were expected to announce their decision in the immediate aftermath of a definitive merger agreement between rival Delta Air Lines and Northwest Airlines. The timing of the events was notable because Northwest's golden shares in Continental (that gave Northwest veto authority against any merger involving Continental) could be redeemed, freeing Continental to pursue a marriage with United. On April 27, 2008, Continental broke off merger negotiations with United and stated it was going to stand alone. Despite ending merger talks, Continental announced that it would join United in the Star Alliance.
United and US Airways were in advanced merger talks in late April 2008, following the announcement that Continental had broken off talks with United. In June 2008, CEOs of both United Airlines and Continental Airlines signed an alliance pact presaging their eventual merger. The alliance is an agreement to link international networks and share technology and passenger perks. This agreement is basically a "virtual merger" that includes many of the benefits of a merger without the actual costs and restructuring involved. The alliance took effect about a year after Delta Air Lines and Northwest Airlines completed their merger, as that released Continental from the SkyTeam contract and allowed for the required nine-month notice. Additionally, Continental joined Star Alliance, as Delta and Northwest merged.
United Airlines was reported to be in serious merger discussion with US Airways in early April 2010. A New York Times report indicated that a deal was close. Union consent was cited as a major hurdle for negotiators to clear. On April 22, 2010, United announced that it would not pursue a merger with US Airways.
The Board of Directors at Continental and United Airlines approved a stock-swap deal that would combine them into the world's largest airline on Sunday, May 2, 2010. The airlines publicly announced the deal the next day. This would re-unite Walter Varney's airlines, which offspring includes Continental and United.

Both airlines have taken losses in the recession and expect the merger to generate savings of more than $1 billion a year. Combined, they fly to some 370 destinations in 59 countries from their ten hubs, and carry 144 million passengers a year. Combined revenues will be about $29 billion.
In July, the merger of the two airlines was approved by the European Union.
On August 27, 2010, the U.S. Department of Justice approved the $3 billion merger and shareholders of both the companies approved the merger on September 17, 2010. On October 1, 2010, UAL Corporation (the parent company of United Airlines) completed its acquisition of Continental Airlines and changed its name to United Continental Holdings, Inc. Although the two airlines remained separated until the operational integration was completed, as of this day both airlines are corporately controlled by the same leadership. Both carriers achieved a single operating certificate from the FAA on November 30, 2011 which allowed both airlines to operate under the name "United".

## Branding

When United Airlines and Continental Airlines announced their merger in May 2010 they introduced their new corporate branding. It featured the words "United Airlines" in the then-current Continental typeface, and Continental's globe-like logo. United updated their branding once again in August 2010, replacing the words "United Airlines" with the single word UNITED and changing the font to United's traditional upper-case sans-serif font. United's new CEO Jeff Smisek, who previously served as Continental's chairman, helped design the new font, integrating it with the existing Lippincott-designed Continental graphics. He has noted that he has received over 15,000 emails with suggestions for a new livery.
Re-painting and branding started in late-2010 and is said to be "accelerated" by early-to-mid-2011.
On March 1, 2011, United unveiled an "interim" marketing campaign replacing the previous "It's Time to Fly" campaign, which included fingerpaint ads and television spots created by Fallon. On the same date, United removed the iconic 38-year-old Saul Bass-designed "Tulip" logo from its website and all new advertisements will feature the former Continental globe logo. This new campaign was used until 2012, when United reconditioned a former slogan, "Fly the Friendly Skies".
