VivaColombia

Fast Colombia S.A.S., trading as Viva Air Colombia and formerly VivaColombia, was a Colombian ultra low-cost airline based in Rionegro, Antioquia, Colombia. It was a subsidiary of Irelandia Aviation and, as of its bankruptcy in March 2023, the third largest airline in the country. The company was not legally affiliated with Mexico's Viva Aerobus, another low-cost carrier co-founded by Irelandia which also uses the "Viva" brand, although they did have a codeshare agreement for their flights. The company filed for insolvency in February 2023, and on February 27, 2023, the airline suspended, and eventually ceased, all operations, citing rising fuel prices and Aerocivil's failure to approve its planned acquisition by Avianca.
