On October 1, 2010, UAL Corporation and Continental Airlines merged to form United Continental Holdings, the holding company for the newly merged United Airlines. On June 27, 2019 United Express changed its parent company name from United Continental Holdings to United Airlines Holdings. As Continental and United merged, Continental Connection and Continental Express gradually adopted the United Express brand name, bringing the number of operators to twelve and the number of aircraft to over 550. The first aircraft painted into the new United Express livery of 2019 was an Embraer E175 operated by ExpressJet.
As of November 30, 2011, after United received its Single Operating Certificate following the merger with Continental Airlines, over 575 aircraft fly under the United Express brand.
Major airlines in the United States had long maintained relationships with regional carriers which fed passengers from small markets to larger cities. The Airline Deregulation Act spurred industry consolidation both vertically and horizontally, and as the hub system became more pronounced, airlines formalized these relationships through code sharing, shared branding, and listing regional partners in computer reservations systems. On May 1, 1985, United formally partnered with Air Wisconsin, Horizon Air, and WestAir as United Express, feeding its hubs at Chicago-O'Hare, Seattle International Airport, and San Francisco International Airport. Aspen Airways soon joined the United Express system in 1986 feeding United's hub at Denver-Stapleton. Aspen was dismantled in 1990 being sold to Air Wisconsin and Mesa Airlines. Horizon Air was bought out by Alaska Airlines in 1987 at which time Horizon's contract as United Express was cancelled and a new carrier, North Pacific Airlines (NPA), was established by WestAir to service the Seattle hub as well as hubs at Portland, Spokane, and Boise. NPA was merged into its parent, WestAir, in 1991. San Juan Airlines of Seattle and SouthCentral Air of Anchorage, Alaska, also operated as United Express from 1987 through 1989.
In 1988, Presidential Airways became a United Express carrier for United's new hub at Washington Dulles International Airport, but soon floundered. In response, WestAir formed an eastern division to serve Dulles. WestAir itself experienced turmoil; in 1991 it spun off the new division into an independent company, Atlantic Coast Airlines (ACA), which years later would go on to become Independence Air.
In 1990, Mesa Airlines took over all of the United Express routes from Denver formerly operated by Aspen Airways except the Denver to Aspen route which went to Air Wisconsin. Mesa also added a number of new routes from Denver as well. In 1992 Mesa created a new division called CalPac to begin new United Express service from the Los Angeles hub. In 1995 Mesa took over all United Express routes at the Seattle and Portland hubs formerly operated by WestAir. Mesa Airlines contract operating as United Express was cancelled in 1998 at which time Air Wisconsin and Great Lakes Airlines took over the Denver routes while SkyWest took over the Los Angeles, Seattle, and Portland routes.
In 1992, Great Lakes Airlines became a United Express partner, followed by Trans States Airlines the following year. In 1997, as United officially designated Los Angeles International Airport one of its hubs, SkyWest Airlines became a United Express partner as well. Great Lakes left the United Express system in early 2002, although it continued to do codeshare flights until they ceased operations in 2018.
In 1993, Trans States Airlines started United Feeder Service (UFS), to operate British Aerospace BAe ATP aircraft for United Airlines. The aircraft, originally owned by Air Wisconsin, were transferred and subsequently owned by United. UFS operated routes to Chicago O'Hare (ORD) from close markets in the U.S. Upper Midwest. UFS was eliminated from the United Express carrier network in 1999 and disappeared.
When United declared for Chapter 11 reorganization in 2002, it pressured its regional partners for reduced fees. In 2004, ACA canceled its contract and reinvented itself as low-cost carrier Independence Air. The next year, Air Wisconsin unsuccessfully bid to retain its flying contract, though it did retain some ground-handling United Express operations. To compensate, United initiated new service agreements with Colgan Air, Trans States subsidiary GoJet Airlines, and Republic Airways Holdings subsidiaries Chautauqua Airlines and Shuttle America. Mesa Airlines was also reinstated into the United Express system.
In 2005, United announced that service levels on major United Express routes would be upgraded to a new product called explus. Routes with explus service offer First Class seats and meal service on larger, 70-seat Embraer 170s and 66-seat Bombardier CRJ700s. Expanding the traditional regional partner role, United started to use the airplanes configured with explus amenities instead of, or alongside with, mainline jets on routes linking large cities, such as Chicago to Houston.
United decided to cancel Dash 8 and CRJ-200 service with Mesa Airlines in November 2009. On November 16, 2009 it was announced that ExpressJet would begin operating Embraer ERJ-145 beginning in the spring of 2010. Mesa Airlines continued service using CRJ-700 regional jets and added the Embraer 175 in 2015.
All Continental Express and Continental Connection service officially merged into United Express in late 2011 including that of Cape Air which was operating as Continental Connection on behalf of Continental Micronesia in Guam. Silver Airways was also a Continental Connection carrier that converted to United Express using turbo prop aircraft. Silver operated throughout Florida as well as routes from Washington Dulles Airport however their affiliation as United Express ended in 2013.
On April 1, 2012, Pinnacle Airlines Corp. filed for bankruptcy and announced it would draw down its Colgan Air operation. In May, United reached a deal with Republic Airways Holdings for its subsidiary Republic Airways to fly the Q400 in Colgan's place. The eight-year capacity purchase agreement included all 28 aircraft previously operated by Colgan as well as four currently flown by Republic for Frontier Airlines.
In August 2015, United announced the start of a new subsidiary, United Ground Express, to provide ground operation service in select airports within its domestic network.
On February 27, 2017, United Airlines announced the return of their partnership with Air Wisconsin as a United Express carrier. They would be flying a fleet of 65 Bombardier CRJ-200 beginning second-half 2017.
In September 2017, the Dash-8-Q300 was phased out and in January 2018, the Dash-8-Q200 was phased out. These were the final prop aircraft in the United Express system within the United States.
On April 16, 2018, United Airlines announced the end of its partnership with Cape Air. Services ended on May 31, 2018, which marked the end of United Express operations in Guam, along with the retirement of the last turboprop aircraft in the United Express fleet.
On July 30, 2020, it was announced that United Airlines had decided to end its contract with ExpressJet and transferred these operations to CommutAir. ExpressJet continued its operations until September 30, 2020 and CommutAir became the sole operator of the United Express Embraer ERJ-145 fleet.
At the beginning of 2021, six airlines remain as United Express feeder carriers: Air Wisconsin, CommutAir, GoJet, Mesa Airlines, Republic Airways, and SkyWest Airlines. Most of these carriers now have routes spanning the entire United States with regional jets. SkyWest serves a number of small cities that are subsidized by the federally funded Essential Air Service program as well as other local and state governments.
United Express bus service connects Beaumont/Port Arthur to George Bush Intercontinental Airport (IAH). This service began after Colgan Air-operated Saab 340 turboprop flights ended on July 1, 2012, and this bus service continues at present with several trips a day.
United Express also has a bus service from Lehigh Valley International Airport (ABE) near Allentown, Pennsylvania to Newark Liberty International Airport (EWR). Continental Airlines, which later merged into United, previously operated flights from Allentown to Newark but switched to a bus service in 1995 due to constant delays from air traffic control. It is 79 miles (127 km) long. As of 1997 the service was eight times daily. By February 2010 the bus was the only form of service offered by Continental after it cancelled its Allentown to Cleveland Hopkins Airport flights.
