Through SCADTA, Avianca is the world's second oldest extant airline after KLM, and celebrated its 100th anniversary in December 2019. It is the oldest airline in the Western Hemisphere. It became an official member of Star Alliance on 21 June 2012, after a process that lasted approximately 18 months from the initial announcement of its invitation to join the alliance. On May 10, 2020, Avianca filed for Chapter 11 bankruptcy in a court in New York City, NY, United States, and liquidated its subsidiary Avianca Peru, becoming one of the major airlines to have filed for bankruptcy due to the COVID-19 pandemic crisis.
