Transportation
Despite the growth and development of transport infrastructure elsewhere in the country, Karachi remains the country's transport hub. The city's two ports, Port of Karachi (Pakistan's largest) and Port Qasim, are central to nearly all shipping in Pakistan. The airport of Karachi, Jinnah International Airport (also known as Quaid-e-Azam International Airport) is the largest and busiest airport in Pakistan and handles 6 million passengers a year. The airport also receives the largest number of foreign airlines; a total of 27 airlines fly to Jinnah International, predominantly from the Middle East and South East Asia. All of Pakistan's airlines use Karachi as their primary hub, including Pakistan International Airlines, Aero Asia International, Airblue and Shaheen Air International.
