Phoenix Sky Harbor International Airport (PHX) serves Phoenix, United States, and sits just 3.5 miles from the city center, making it one of the more conveniently placed major airports for travelers. The airport lies at an elevation of 1,135 feet.

Sky Harbor functions primarily as a major domestic hub, with a route network heavily weighted toward destinations across the United States, spanning the East Coast, the central and southern regions, and other parts of the West. Its traffic pattern reflects strong connectivity to large metropolitan hubs throughout North America, alongside a meaningful international component reaching into Canada. This mix underscores the airport's role as a significant connecting point for domestic travel within the United States, while still offering cross-border links to the north.

Given its scale and the breadth of destinations served, travelers passing through Phoenix Sky Harbor can expect frequent service to a wide array of American cities, making it a practical option for both origin and connecting itineraries. The airport's low elevation and desert location mean travelers should be prepared for the operational conditions typical of a major low-altitude hub in a hot, arid climate.
