mas (legally Aerotransportes Mas de Carga, S.A. de C.V. and formerly known as MasAir) is a Mexican cargo airline based in Mexico City, Mexico, specialized in the transport of air cargo utilizing wide-body aircraft. The airline operates scheduled and charter services across the Americas, Asia and Europe, from its main hub Felipe Ángeles International Airport, with secondary hubs at Los Angeles, and Zaragoza through its subsidiary Galistair Malta.
The airline was established in 1992 and commenced operations in April 1995. Initially branded as MasAir, the carrier focused on regional cargo routes, primarily connecting Mexico with the United States and Colombia.
In December 2000, LAN Airlines (later LATAM Airlines) acquired a 25% stake in the company, which eventually grew to nearly 70%. During this period, the airline underwent significant modernization with the addition of Boeing 767 to replace the older Douglas DC-8s.
In May 2016, as part of the consolidation of LAN and TAM brands, the airline was rebranded as LATAM Cargo Mexico and the carrier became a vital link in the LATAM Cargo network.
On December 1, 2018, LATAM Airlines Group sold its stake to Discovery Americas, a Mexican private equity firm. This marked the carrier’s return to independence.
In early 2022, the airline dropped the “Air” from its name, officially rebranding as mas. The new brand identity was designed to reflect the ambitious expansion strategy. Along this new era, mas made history by becoming the first airline in the Americas to operate the Airbus A330 P2F cargo variant.
In December 2022, mas purchased a 49% stake in Maltese charter Galistair Malta, allowing the Mexican carrier to expand their global network.
