King Fahd International Airport, also known as Dammam International Airport or simply Dammam Airport or King Fahd Airport, is the international airport serving Dammam, Saudi Arabia. The airport is located 31 kilometres northwest of downtown Dammam and is named after the former King of Saudi Arabia, Fahd ibn Abdulaziz. The airport serves the entire Eastern Province of Saudi Arabia and is one of the three primary international airports in the kingdom. King Fahd International is also the largest airport in the world by area, with the area of the airport property being an approximate 776 square kilometres, even though the airport building itself is just 36.75 km2.
The third largest airport in the kingdom by passenger volume, more than 10 million passengers use King Fahd International each year, and 37 airlines operate flights in and out of the airport. The airport serves as a hub to Saudia, SaudiGulf Airlines and Flynas. It previously served as a hub to the now defunct Sama airline. In addition to these airlines, Saudi Aramco Aviation, the airline operated by Saudi Aramco, the state-owned oil giant; which uses it to transport employees in and out of strategic locations such as Yanbu, Tanajib and Shaybah, also flies out of the airport.
The airport is named for King Fahd (r. 1982–2005), under whose reign it was constructed and inaugurated. Design of the airport building began in 1976. The site master plan was created by architecture firm Yamasaki & Associates and Boeing and completed in 1977, with construction beginning in 1983.
The airport is classified as Code E by the ICAO which means aircraft such as the Boeing 747-400 and A340-600 could be easily accommodated. It is practically possible for an A380 to use the airport, but this is not recommended as in order to accommodate such aircraft, an airport is required to be Code F; only the runways at Dammam Airport meet Code F requirements; the taxiways and gates do not.
