A mainline flight is a flight operated by an airline's main operating unit, rather than by regional alliances, regional code-shares, regional subsidiaries, or wholly-owned subsidiaries offering low-cost operations. Mainline carriers operate between hub airports within their network and on international or long-haul services, using narrow-body and wide-body aircraft; this is in contrast to regional airlines, providing feeder services to hub airports operating smaller turboprop or regional jet aircraft, or low-cost carrier subsidiaries serving leisure markets. In the United States, examples of mainline passenger airline flights include those operated by American Airlines, Delta Air Lines, United Airlines. U. S. legacy carriers may operate branded mainline services using the same flight crews and AOC as that of their mainline operations. For example, United p.s. and American Flagship Service cater to the medium-haul transcontinental business segment. Short-haul air shuttles, such as Delta Shuttle, operate at high frequency intervals between busy city pairs.
U. S. legacy carriers operated low-cost air services within their mainline operations to compete with low-cost carriers. Outside the U. S. low-cost carrier subsidiary airlines are more common, with examples including Air Canada Rouge, Jetstar Airways, Eurowings. An airline carrier's collective bargaining agreement with flight crews stipulates the maximum seating capacity of regional aircraft; the converse is not the case.

Business model of new Airlines like GLO not operating their own aircraft but leasing them from other certificated air carriers, creating their own airline brand without the actual assets of a true airline
Horizon Air Industries, Inc. operating as Horizon Air, is a regional airline based in SeaTac, United States. Horizon Air and its sister carrier Alaska Airlines are subsidiaries of Alaska Air Group and all Horizon-operated scheduled flights are marketed and sold by Alaska Airlines. Planes operated by Horizon are co-branded as "Alaska Horizon" in recognition of the Horizon brand and to differentiate aircraft from those operated by Alaska's other regional airline partner, SkyWest Airlines. Horizon Air was once the eighth largest regional airline in the US, serving 42 cities in the United States and Canada, it was purchased by Alaska Air Group in November 1986 and continued to fly as a separately branded airline until 2011, when it shifted to the current capacity purchase agreement business model. Horizon Air was formed in May 1981 by Milt Kuolt, started operations on September 1, 1981, with three Fairchild F-27 aircraft, its headquarters were in an area, now within SeaTac, Washington. Horizon Air's first route was from Yakima to Seattle and one week Pasco to Seattle.
The general offices of Horizon Air were operated out of an old house behind Sea-Tac airport. Horizon acquired Air Oregon on June 17, 1982, after both airlines were losing hundreds of thousands of dollars monthly, in order to consolidate and reduce their operating deficit. Horizon agreed to purchase Transwestern Airlines of Utah in September 1983, once again to try to reduce operating deficit of the airline. A single Fokker F28 Fellowship twin jet, purchased in July 1984 from an African carrier, was the first jet owned by Horizon Air. An initial public offering occurred in 1985 to secure operating capital, which after only one profitable year since founding, was needed to keep the airline afloat. In the summer of 1985, Horizon entered into its first codeshare agreement with United Airlines; that year, on September 8, 1985 Horizon signed an agreement with de Havilland Canada to begin purchasing the airline's first brand new aircraft, the de Havilland Canada Dash 8-100 twin turboprop. Late in 1985 Horizon entered into an agreement to purchase their chief competitor in Washington, Cascade Airways, but by early 1986 were released from the agreement.
In January 1986, the airline became an international carrier when it began service to Calgary, Alberta, in association with Cascade Airways. Alaska Airlines struck a deal to acquire Horizon Air in November 1986; the year before, Alaska had underwent a major corporate restructuring with the airline now being owned by the Alaska Air Group, an airline holding company. Under the agreement, the Alaska Air Group became the owner of Horizon Air after approval by the Transportation Department in late December; the Alaska Air Group continued to operate Horizon as a separately branded airline, with a codesharing agreement with its new sister airline, Alaska. In 1988, Horizon signed a code share agreement with Northwest Airlines. International service was expanded in May 1989 with flights to Vancouver and Victoria in British Columbia, using both Dash 8-100s and Fairchild Swearingen Metroliner turboprop aircraft. Horizon was the launch customer for the Dornier 328 turboprop, intending to replace the Metroliners with this new aircraft which promised speed and comfort on par with jetliners.
In recognition of the order, Dornier painted its second prototype of the 328 in Horizon colors. Twelve aircraft were delivered between November 1993 and November 1995, but they were phased out in 1997 in favor of fleet standardization to the Dash 8 series of turboprops. Throughout its history, Horizon has either operated as a standalone carrier or as a regional affiliate of Alaska Airlines for most of its history, except between 2004 and 2007 when it operated Bombardier CRJ-700 aircraft on the behalf of Frontier Airlines. In late 2010, Horizon's parent company, the Alaska Air Group, made the decision to no longer operate Horizon as a separate regional airline. Starting on January 1，2011, Horizon shifted to a capacity purchase agreement business model, which had by that time become the regional airline industry standard. Under the CPA, Horizon operates and maintains its aircraft, while Alaska Airlines is responsible for scheduling and pricing all flights; as part of the change to the new business model, the Horizon Air brand was retired and all Horizon planes were repainted with a co-branded "Alaska Horizon" livery.
Alaska Airlines entered into a similar capacity purchase agreement with SkyWest Airlines in May 2011. As part of the agreement, Alaska Air Group managers agreed to sell Horizon's fleet of five Bombardier CRJ-700 regional jet aircraft to SkyWest, which used the aircraft to operate six West Coast routes as "Alaska SkyWest"; the move left Horizon with a fleet consisting of a single type of aircraft. Horizon announced in April 2016 that it would expand its fleet and once again operate regional jets, placing an order for 30 Embraer 175 airplanes; the order is the largest in the airline's history and was expanded to 33 jets. The airline experienced a period of turmoil in 2017. Amid unprecedented growth, Horizon experienced a severe pilot shortage, forcing the airline to cancel hundreds of flights and delay delivery of new aircraft; the pilot shortage was part of a broader problem affecting all regional airlines, but hit Horizon hard. After the airline industry started to rebound in 2013 after a decade long downturn, mainline air carriers started to hire pilots from regional carriers which offer low wages and limited opportunities for advancement.
Horizon responded by drastically increased pay for flight crews and worked with Alaska, its sister airline, to create more o

Its main base is Philadelphia International Airport with an additional hub at Charlotte Douglas International Airport; the airline was formed in 1961 by Richard A. Henson as Henson Aviation, a fixed-base operator in Hagerstown, Maryland, it began its first scheduled flights to Washington National Airport in 1962 under the Hagerstown Commuter name changed to Henson Airlines. Allegheny Airlines and Henson began one of the world's first code sharing arrangements in 1967. Henson re-branded itself as an Allegheny Commuter carrier using Beechcraft 99 aircraft.
It developed a route structure serving Washington D. C. Philadelphia and Baltimore, while establishing a new headquarters for Allegheny Commuter at Salisbury, Maryland in 1968. In the 1970s, the airline upgraded to Short de Havilland Canada DHC-7 Dash 7 turboprops. In 1983, Piedmont Aviation bought Henson and re-branded the airline as "Henson, The Piedmont Regional Airline." Under Piedmont's control, the airline expanded particularly in Florida. Both were purchased by the USAir Group in 1987 with Piedmont absorbed two years and Henson's aircraft repainted in USAir Express livery; the 1980s saw rapid growth by the company with the upgrade of its fleet to the de Havilland Canada Dash 8 aircraft and fleet expansion. With the growth in capacity, the airline expanded to Florida, including numerous intrastate routes in Florida, it opened a maintenance facility in Jacksonville; the Piedmont name was resurrected in 1993, when USAir renamed Henson to "Piedmont Airlines", to protect the Piedmont brand name, which could be used by others if not exercised in trade use for a period of time.
USAir continued this practice by changing the name of its two other wholly owned regional airline subsidiaries and Suburban Airlines, to PSA Airlines and Allegheny Airlines, respectively. In 1997, USAir was renamed US Airways, Piedmont and Allegheny were re-branded as US Airways Express carriers. US Airways merged Allegheny Airlines into Piedmont in 2004; the airline had more than 7,000 employees, as of December 2017.

The crash was fatal to all both crewmembers. S. pilot, First Officer Zilda A. Spadaro-Wolan; the National Transportation Safety Board concluded that part of the probable cause of the crash was the airline's failure to standardize the cockpit configurations of its aircraft and on its failure to provide adequate training to its pilots. On November 16, 2008, Flight 4551, a US Airways Express de Havilland Dash-8 turboprop operated by Piedmont Airlines, took off from Lehigh Valley International Airport at 8:20am heading to Philadelphia International Airport, had to make an emergency landing; the flight crew was indicated that the front nose gear hadn't come down and had to make a flyover the runway for confirmation. Of 35 passengers and 3 crew, there were no injuries; the aircraft was returned to service shortly thereafter. On January 1, 2011, US Airways Express Flight 4352, a Piedmont Airlines-operated de Havilland Dash-8 turboprop forced an evacuation of the U. S. Capitol and fighter jets were scrambled from Andrews Air Force Base after Flight 4352 suffered radio problems on approach to Washington, DC's Ronald Reagan Washington National Airport and strayed into restricted airspace.
The Capitol was evacuated for 20 minutes until the Dash-8 aircraft landed at Reagan National Airport. On January 7, 2011, a Bombardier Dash 8-100, operating as Piedmont Airlines Flight 4507 under US Airways Express from Philadelphia International Airport to Tweed New Haven Regional Airport in Connecticut was struck by lightning over the Long Island Sound; the captain reported electrical problems and diverted safely to Long Island Macarthur Airport due to more favorable weather conditions. The aircraft had 33 passengers aboard who were bussed to New Haven. On May 18, 2013, US Airways Express Flight 4560 made a belly landing at Newark Liberty International Airport after landing gear would not extend. All passengers and crew members were evacuated safely; the airline began sponsoring NASCAR as the primary sponsor for Ricky Rudd and Richard Childress Racing in 1982.

Mesa Airlines, Inc. is an American regional airline based in Phoenix, Arizona. It is an FAA Part 121-certificated air carrier operating under air carrier certificate number MASA036A issued on June 29, 1979, it is a subsidiary of Mesa Air Group and operates flights as American Eagle and United Express via respective code sharing agreements with American Airlines and United Airlines. It serves more than 180 markets in the Western Hemisphere. In a 1997 article from the Journal of Air Transportation, Mesa's safety record was noted as having the fewest incidents among domestic regional airlines At that time. Mesa filed for Chapter 11 bankruptcy in January 2010, hoping to shed financial obligations for leases on airplanes it no longer needed, emerged from bankruptcy in March of 2011. Since 2013, Mesa has added more aircraft to its fleet than any other regional airline. In November 2017, Mesa opened a new training center in Phoenix; the 23,000-square-foot facility features a full-size CRJ-200 cabin trainer aircraft, 14 classrooms, has the capacity to train 300 crew members at one time.
Mesa Airlines operates as: the regional marketing brand of American Airlines. Mesa began flying routes as American Eagle in 2014 from American's hubs in Dallas/Fort Worth and Phoenix using Bombardier CRJ900 regional jet aircraft. United Express, a mainline airline marketing sub-brand using United Express liveried fleet of Bombardier CRJ700 and Embraer 175 aircraft under a revenue-guarantee code sharing agreement, its hubs are at Washington Dulles for the CRJ700 aircraft. Air Midwest CalPac Desert Sun Airlines FloridaGulf Airlines Go! Liberty Express Airlines Mountain West Airlines Skyway Airlines Superior Airlines Mesa began operations as Mesa Air Shuttle in Farmington, New Mexico, in 1980. From 1989 through 1998, Mesa Airlines operated as a conglomeration of up to eight separate airlines. For the history of the acquisition and expansion of Mesa Airlines during this time see Mesa Air Group; the following history section details the history of the individual airlines that comprised Mesa Airlines during this time frame.
The original Mesa Air Shuttle was a flight division of JB Aviation in Farmington, New Mexico and operated a single route from Farmington to Albuquerque using a Piper Saratoga aircraft. In 1981 as the original Frontier Airlines was discontinuing its flights between the two cities, Mesa obtained a twin engine Piper Navajo Chieftain and increased service on the route. In 1982 the original owners sold the company to Janie Risley; the Risley's expanded the carrier by acquiring a fleet of 14-passenger seat Beechcraft 99 commuter turboprops and adding service throughout New Mexico and surrounding states with a hub at Albuquerque. In 1985 larger 19-passenger seat Beechcraft 1900's were acquired which replaced the Beech 99's and became the backbone of Mesa's fleet. By 1987 up to 47 daily departures were operating from Albuquerque to 18 cities. In 1987 a Denver hub was created when Mesa acquired Centennial Airlines which operated several routes from Denver into Wyoming. After an initial route from Farmington and Gallup to Phoenix began in 1985, Phoenix was expanded into a hub in 1989 with new routes throughout Arizona.
In 1990, most Denver flights were incorporated into the United Express division which Mesa had acquired from Aspen Airways. In 1992, when Mesa established a code share with America West Airlines, its Phoenix hub was turned over to the America West Express division. A minor hub was operated at Farmington in the late 1980s with up to 22 daily flights connecting Albuquerque and Salt Lake City to Durango and Telluride, CO. For a brief time in 1995 and 1996, the Mesa Airlines operation at Albuquerque, the United Express operation in Denver, the America West Express operation in Phoenix were all known as operated by Mountain West Airlines. In 1997 and 1998, routes from Little Rock to Nashville and Wichita and from Nashville to Tupelo were added, first as Mesa Airlines later as US Airways Express. In 1997, Mesa established a small hub at Fort Worth Meacham International Airport, using two Bombardier CRJ200 regional jet aircraft, providing service from Fort Worth to San Antonio and Houston Hobby, as well as new routes from Colorado Springs to Nashville and San Antonio.
The venture was short-lived and these routes were all eliminated during corporate restructuring. The Albuquerque hub was merged into Air Midwest in 2001 but operated as a code share for Mesa Airlines until the hub was dissolved at the end of 2007. In 1998, Mesa moved its headquarters from Farmington, NM to Phoenix, AZ. In September 1992, Mesa negotiated a code sharing agreement with America West Airlines to operate as America West Express out of its Phoenix hub, serving 12 cities; these routes were from the independent Mesa operation and several Beech 1900D aircraft were painted in the America West Airlines scheme. The code share allowed increased frequency and increased load factors and expansion into several new markets. In 1995, Mesa created a new subdivision called Desert Sun Airlines and acquired a pair of Fokker 70 jets for use on new America West Express routes from Phoenix to Des Moines and Spokane. Desert Sun was merged into the Mesa Airlines division in 1997 and its Fokker 70 aircraft were replaced by Canadair CRJ-200 regional jet aircraft.
The CRJ-200 aircraft began replacing the Beechcraft 1900D and Embraer EMB-120 Brasilia turboprops. The BE-1900Ds were transitioned over to Mesa's Air Midwest subsidiary. Beginning in December 1997, Mesa began operating de Havilland Canada DHC-8 Dash 8 series 200 aircraft between Ph

In December 2011, Air Choice One was awarded a one-year EAS contract to replace SeaPort Airlines in Jonesboro, Arkansas with the date to begin service set at February 13, 2012. In January 2013 the DOT granted Air Choice One a three-year contract extension for both Decatur and Burlington, Iowa; as a stipulation for obtaining both extensions Air Choice One implemented systems for electronic ticketing and baggage agreements via WorldSpan in December 2012.
This allows passengers to book tickets with connections to and from other major airlines on popular travel websites in a "one-click" process, as opposed to buying tickets at one airline and having to book tickets with another on two separate confirmations. In February 2014 Air Choice One was awarded by the DOT a four-year extension on its EAS contract to serve Jonesboro, Arkansas. In the same month, there were three proposals sent out by them to the following cities for EAS service: Ironwood, Fort Dodge and Mason City, Iowa. In March 2014 Muscle Shoals, Alabama city and airport leaders visited the Air Choice One headquarters to consider its EAS contract bid for Northwest Alabama Regional Airport, however the contract was awarded to SeaPort Airlines and Boutique Air to begin service in 2016. In 2011, Air Choice One submitted a proposal to the US DOT to serve Muscle Shoals with flights to either Atlanta, Nashville or Memphis. Pending acceptance of the proposal, the airline was planning to begin flights in as little as 30 days.
The airline never commenced service to Muscle Shoals. On April 18, 2014 the DOT awarded Air Choice One a two-year contract to serve Ironwood, Michigan with service to and from Chicago, Illinois, it began service in the summer of 2014. On August 19, 2014, Air Choice One was awarded a two-year contract from the DOT to serve Mason City, Iowa with service to and from Chicago, Illinois, it began service on November 17, 2014. On December 21, 2017 Air Choice One was granted a four year contract extension in Burlington and was not selected for another term in Decatur, marking the end of Air Choice One's nearly eight years of service to Decatur Airport. On January 18, 2018 Air Choice One was approved by the DOT to begin service to Atlanta Hartsfield-Jackson International Airport from Jackson, Tennessee for a term beginning on March 1, 2018 until May 31, 2021. On March 14, 2018 the airline passed the FAA mandated proving runs with its Beechcraft 1900C, meaning that the aircraft is now approved to be used in daily line operations.
Air Choice One began operating the aircraft between Fort Dodge and both Minneapolis and St. Louis in May 2018 and continues to bid other essential air service routes proposing to use the Beechcraft 1900. Effective February 1, 2019 the 3-letter ICAO prefix changed from WBR to ACO. Air Choice One does not participate in any major global airline alliances, nor does it have any codeshare agreements.
