Beijing Capital International Airport (PEK) serves the city of Beijing, China, and lies approximately 18 miles from the city center. The airport sits at an elevation of 115 feet above sea level, a low-altitude setting typical of major coastal and inland hub airports in the region.

Traffic through Beijing Capital International Airport reflects a strong domestic Chinese network alongside connections that extend into the wider East Asian region. The airport functions as a key gateway linking Beijing to other major Chinese cities, while also supporting flights that bridge mainland China with nearby international destinations. This dual role underscores its importance both as a domestic hub within China and as a connecting point for regional air travel across East Asia. Travelers using this airport can expect a mix of short-haul domestic routes and longer regional flights, reflecting Beijing's status as a major population and economic center. The scale of operations suggests a high volume of both business and leisure travel, consistent with the airport's role serving one of the world's largest metropolitan areas. Its relatively low elevation and proximity to the city make it a convenient access point for travelers heading into central Beijing, whether arriving from other parts of China or from destinations elsewhere in the region.
