Islamabad International Airport — Attock, Pakistan

ISB opened in 2018 as Pakistan's newest major gateway, built on a greenfield site well outside the city near Attock to replace the older, more congested Benazir Bhutto International Airport that had served Islamabad and neighboring Rawalpindi for decades. Designed with a single large terminal meant to accommodate long-term passenger growth, the airport quickly became the busiest in Pakistan by some traffic measures, hosting Pakistan International Airlines alongside a range of Middle Eastern, Chinese, and other foreign carriers. Its location, roughly midway between Islamabad and the industrial city of Peshawar, places it within reach of a broad catchment area extending across Pakistan's Punjab and Khyber Pakhtunkhwa provinces. Ground transport into central Islamabad takes longer than travelers experienced with the old airport, a trade-off frequently debated locally, though the newer facility's expanded capacity and modern design have generally been welcomed as the country's aviation demand continues to climb.
