When Armenia declared its independence from the Soviet Union in the 1990s, the growth of cargo shipments resulted in the construction of a new cargo terminal in 1998 that can handle about 100,000 tonnes of cargo annually.
In 2001, a 30-year concession agreement for the management of operations at the airport was signed with Armenia International Airports CJSC, owned by Argentine company Corporación America, which is in turn owned by Armenian Argentine businessman Eduardo Eurnekian. As part of that agreement, Armenia International Airports CJSC renovated the runway, main taxiways and ramp.
In 2006, a new gate area and arrivals hall opened, followed by an overall improvement of the airport's fire services, including replacing the entire fire-fighting fleet with new vehicles.
