Spread across about 780 square kilometers, it is larger than many cities.

Its vast complex includes multiple terminals, a royal terminal, mosques, residential areas, and extensive cargo facilities. Designed to handle future growth, the airport reflects the scale and ambition of modern aviation infrastructure, symbolizing how airports today are not just transport hubs but self-contained cities supporting global travel and trade.
