Mexicana de Aviación Mexicana de Aviación Compañía Mexicana de Aviación, S.A. de C.V. (commonly known as Mexicana) was Mexico's oldest airline and one of the oldest continuously single-branded airlines (after KLM, Avianca and QANTAS), and Mexico's biggest and flagship airline before ceasing operations on August 28, 2010. The group's closure was announced by the company's recently installed management team a short time after the group filed for Concurso Mercantil (Mexican law equivalent to US Chapter 11) and US Chapter 15. On April 4, 2014, a judge declared Mexicana bankrupt and ordered to start selling off the company's assets to repay the airline's obligations.
