Aeroméxico is the nation’s flag carrier, operating on domestic and international routes around North and South America, the Caribbean, Europe and Asia. With its main hub at Mexico City International Airport and secondary hubs at Guadalajara International Airport, Monterrey International Airport and Hermosillo International Airport, the airline reported revenue to the value of 3.1 billion U.S. dollars in 2016. Aeroméxico is the largest domestic airline but is competing with three low-cost carriers in terms of market share: Interjet, Volaris and VivaAerobus. Mexican ultra-low cost carrier, Volaris, reported a net profit of about 170 million U.S. dollars in 2016, for example.
