King Fahd Airport covers an area of approximately 776 square kilometers, 31 kilometers northwest of downtown Dammam City which is the sixth-most populous city in Saudi Arabia. Plans for the construction of the airport commenced back in 1970.
The site master plan was created by architecture firm Yamasaki & Associates and Boeing and completed in 1977, and the construction works begun in 1983. The construction of the basic infrastructure of the airport was complete by the end of 1990, which allowed the U.S-led coalition forces to use the airport during the Gulf War in early 1991 for the storage of military aircraft.
The General Authority of Civil Aviation of Saudi Arabia inaugurated the King Fahd International Airport and opened it for commercial operations on 28 November 1999.
The largest airport in the world is served by two runways, both of which are 4 kilometers long and capable of accommodating larger aircraft including Airbus A340-600 and Boeing 747-400. Parallel to the runways are taxiways and across taxiways, 2.146km long, to connect the two runways.

A six-storey main terminal building with a total area of 327,390m² serves the King Fahd Airport. The third floor of the building is for arrivals, the fourth floor is for boarding, the sixth floor is for departures and the others are for passenger service. The terminal has 11 fixed passenger boarding bridges serving 15 gates.
The airport has two other terminals; the Aramco Terminal, which is used by Aramco employees to board Saudi Aramco Aviation flights; and the 25,000m² Royal Terminal, which is reserved for use by the Saudi royal family and VIPs such as Heads of State, Kings and government officials.

It can be accessed easily from the passenger terminal through two enclosed, air-conditioned bridges equipped with moving belts, in addition to a third open bridge.
