Mexicana de Aviación (1921–2010)

Compañía Mexicana de Aviación S.A. de C.V., usually shortened to Mexicana de Aviación, was Mexico's oldest airline and one of the oldest continuously single-branded airlines, inaugurated in 1921. It was Mexico's biggest airline and flag carrier before ceasing operations on August 28, 2010, leaving competitor Aeroméxico as a de facto monopoly.

A revival airline is operated by SEDENA – the Mexican Ministry of Defense, as a state-owned airline. It began operations in December 2023 under the legal name Aerolínea del Estado Mexicano using the Mexicana brand.
