Tocumen International Airport was inaugurated on June 1, 1947 by President Enrique A. Jiménez, and airport operations began before the construction works were completed. The administrative building/passenger terminal was inaugurated seven years later, during the administration of Colonel Jose Antonio Remon Cantera. The old airport building, which currently is being used as a cargo terminal, was built on an area of and was above sea level. As time passed, and due to Panama's role as a country of transit, that terminal became too small to attend to the growing demand for air operations. These circumstances compelled the aeronautical authorities at the time to consider expanding the airport. Work on the new buildings began in 1971.
