Jinnah International Airport — Karachi, Pakistan

KHI carries the name of Muhammad Ali Jinnah, the lawyer and statesman who led the movement for Pakistan's creation and served as the nation's first governor-general. The airport anchors Karachi, a sprawling port city on the Arabian Sea that briefly served as Pakistan's capital before the government relocated to Islamabad, and that today remains the country's largest metropolis and financial center. As home base for Pakistan International Airlines, KHI has functioned for decades as the country's main international gateway, and during the propeller and early jet era its position along the route between Europe and Australia made it a popular refueling stop for airlines flying what was then called the Kangaroo Route. Karachi's port handles a large share of Pakistan's seaborne trade, and cargo operations at the airport complement that maritime traffic. Ongoing security concerns in past decades have shaped how the facility operates, though passenger numbers have remained substantial throughout.
