Viva

The airline, launched as Viva Aerobus, commenced operations on 30 November 2006, with its hub at Monterrey International Airport, in Monterrey, Mexico, and with an initial investment of $50 million and two Boeing 737-300 aircraft. Viva Aerobus was co-owned by Ryanair's Irelandia Aviation and the Mexican bus company IAMSA. Ryanair joined with Alexander Maurice Mason of Kite Investments to establish "RyanMex" to facilitate the Irish family's investment in the Mexican airline. IAMSA has showed interest in developing a new stage of transportation after its successful bus market in Mexico, and Irelandia has been actively investigating the market opportunity, leading to the companies' partnership to form a Mexican low-cost carrier. Irelandia held a 49% of shares in the airline, while IAMSA had the remaining majority stake.

The airline initially connected Monterrey to a number of Mexican domestic locations, and in July 2007, publicly confirmed its intention to open its first base outside of Mexico and first US destination in Austin, Texas (although it ultimately pulled out of Austin in 2009).

Viva Aerobus fares were intended to undercut traditional Mexican carriers by up to 50%, in a change of the industry that started with the arrival of the country's second generation of low-cost airlines (Avolar, MexicanaClick, Interjet, Volaris) and the privatization of Mexicana de Aviación, one of the two top national airlines. The airline started operations at Monterrey International Airport in November 2006 with two aircraft and one nonstop service connecting Monterrey to Tijuana, under the leadership of Mike Szucs as its CEO. A year after its foundation, in October 2007, Viva Aerobus had already transported one million passengers. Later, Donald Rogers became Viva Aerobus CEO in May 2009, the month when Guadalajara became the airline's second base. In June 2010, the airline's leadership was assigned to Juan Carlos Zuazua, current CEO. Expansion continued and the airline established Mexico City, Cancun, Tijuana and Mérida as its new bases in 2011, 2013, 2015 and 2022, respectively.

On 5 November 2007, the airline received approval from the US Department of Transportation to operate to Austin-Bergstrom International Airport, initially serving the Mexican destinations of Cancún, Monterrey, Guadalajara and León. Flights to the South Terminal Austin began on 1 May 2008.

On 16 May 2009, Viva Aerobus stated it would cease passenger operations at Austin-Bergstrom International Airport on 31 May 2009. The airline blamed the pullout in part on an outbreak of swine flu, which caused an unprecedented decrease in demand for service. The company began to fly between Monterrey and Las Vegas in the summer of 2009.

In November 2009, the airline announced it had applied to commence operations between Hermosillo and Las Vegas beginning in March 2010.

In April 2010, the airline finally began serving Mexico's capital with two flights, one from Monterrey and the other from Guadalajara. It also started serving Houston's George Bush Intercontinental Airport. However, the airline planned to serve Houston Hobby Airport on completion of that airport's new terminal in 2015.

In 2010, the airline opened a focus city at Mexico City International Airport on 1 October after Mexicana ceased operations. Viva Aerobus switched Mexico City from focus city into a hub on 1 April 2011, beginning more destinations from the airport.

On 26 July 2011, the airline received approval to fly to Chicago-Midway International Airport. On 15 August the same year, Viva Aerobus announced it would begin round-trip service between San Antonio (SAT) and Monterrey (MTY), Mexico starting that November. On 13 April 2012, the airline ceased flights to Chicago Midway. On 7 December 2019, the airline resumed flying from Monterrey to Chicago, but this time via O'Hare International Airport. In addition, the airline flew to Morelia, Guadalajara, Leon and Zacatecas from Chicago-O'Hare for the 2019-2020 winter season.

In October 2013, Viva Aerobus has signed an agreement to order 52 Airbus A320 aircraft, consisting of 40 A320neo and 12 A320ceo aircraft, for $5.1 billion, making it the largest order by a Latin American carrier.

On 15 May 2014, Viva Aerobus received and started using Airbus A320s. It continued using Boeing 737s until the end of 2016, when it began operating an all-Airbus fleet.

In October 2014, Viva Aerobus began nonstop flights from Ciudad Juárez (Chihuahua State) to Mexico City, León, and Hermosillo. In 2015, the airline launched flights to Dallas–Fort Worth from several Mexican cities.
