Mexicana de Aviación
In 1993, Aeroméxico acquired 70 percent of the shares worth $54 million, thus making Aeroperú its subsidiary. Subsequently two Boeing 757-200 airliners were transferred, allowing Aeroperú to replace their ageing DC-8s. In 1996, 47 percent of Aeroperú was transferred to Cintra, the parent company of Aeroméxico and Mexicana de Aviación. The three airlines entered mutual codeshare agreements under the Alas de Americas name, with Aeroperú joining "Club Permier", the frequent-flyer program of Aeroméxico. Between 1996 and 1997, Aeropéru maintained a second base at Bogotá's El Dorado International Airport in Colombia, from where regional flights were offered. In 1998, Delta Air Lines became a major shareholder of Aeroperú, when they acquired a 35 percent stake in the airline. The agreement saw Cintra reducing their share to an equal 35 percent.
