On the cargo side, National Airlines operated two Douglas DC-8-63CF's (N921R/N865F) and one Douglas DC-8-71F (N872CA) on scheduled and charter operations worldwide, and later replaced one of the DC-8-63CF's with a DC-8-73F (N155CA). In April 2009, the carrier began cargo flights from Ypsilanti, Michigan, to Bagram Air Force Base in Afghanistan; the flights were extended to Kandahar International Airport in August of that year. This service was discontinued in 2010, with the last working flight for the DC-8 with National taking place in May 2012. During the summer of 2010, the airline purchased three Boeing 747-400BCF aircraft. These 747s were operated for the airline by Air Atlanta Icelandic initially, before being registered in the United States in 2011.
