Islamabad International is the third largest airport of Pakistan. It is the airport for the capital city of Islamabad.
The airport is actually located outside of Islamabad, in the area of Chaklala Rawalpindi. Being the main airport for the Pakistani capital it often hosts officials and citizens from other nations. The airfield is shared with the transport and liaison squadrons of the Pakistan Air Force, which refers to it as PAF Base Chaklala.

It serves as a hub for the national career PIA (Pakistan International Airlines) and Shaheen Air International. It is also a focus city for Airblue.
The airport has a wide variety of duty-free shops, restaurants, wireless Internet services and souvenir arts and crafts shops. There are numerous television monitors and mobile connecting points in the terminal to allow passengers to check flight times and recharge their phones. There are a string of financial exchange counters and commercial banks such as National Bank of Pakistan, Habib Bank Ltd, and MCB Bank Ltd. MCB and Royal Bank of Scotland (formerly ABN AMRO) have also launched ATMs that are linked to the global MasterCard, Cirrus and Maestro networks. To meet safety and health issues, the airport has also newly opened "Smoke Zones" within the lounge facilities. These are designated glass smoke boxes where passengers are allowed to smoke. The smoke is sucked out using the air conditioning so no smoke armours remain or spread within the airport lounges. The design is similar to the ones seen at various international airports.

During October 2005, Islamabad handled additional aircraft that provided aid for the affected people of Kashmir after the 2005 Kashmir earthquake. The largest of these aircraft was the An-225 Myria. Virgin Atlantic Airways also operated a special relief flight to Islamabad using a Boeing 747 with 55 tonnes of aid.
