When Pakistan International Airlines (PIA) acquired its first Boeing 720 Walton was unable to handle the load of a jet aircraft. The Government of Pakistan decided to build a brand new airport, which opened in 1962. The airport had a specifically built runway and apron to handle aircraft up to the Boeing 747. This allowed Lahore to open its gates to the world. PIA initiated direct flights to Dubai and London via Karachi.AIIA TerminalOver the course of the next twenty five years the demand for air travel rose. It meant that the government had to build a new airport to meet the growing needs for of the region. In March 2003, a new terminal was inaugurated by General Pervez Musharraf originally commissioned by then ex prime minister Nawaz Sharif. The airport was named Allama Iqbal International Airport and became the second largest airport in Pakistan after Jinnah International Airport in Karachi. All flights were switched to the new airport and the old airport was passed onto the military. However, the government later reclaimed the airport from the military and developed it into a Hajj terminal.
