The airport achieved international status in 1965 when the first flight was operated from Kabul, Afghanistan to Peshawar. The flight was operated by the national flag carrier, Pakistan International Airlines (PIA). As years went on the airport grew with more flights and aircraft and relative upgrade was carried out from time to time. It was not until 1981 that the CAA extended the terminal to meet future needs for the next decade and to meet the estimated growth of passengers. The apron was developed fully by 1986, where the airport was able to handle four widebody aircraft and two small narrow body aircraft at one time.
