Phoenix Sky Harbor Airport

Phoenix Sky Harbor International Airport, also known as PHX, Sky Harbor Airport, or Phoenix Sky Harbor Airport, is a civil-military public airport located in Phoenix, Arizona, United States. It provides airfield infrastructure, passenger terminals, cargo facilities, and support services for commercial airlines, general aviation, and military operations. The airport serves as a primary gateway for domestic travel within the United States and offers international connections to destinations in Canada, Mexico, Europe, and Asia. It hosts multiple airline hubs and focus cities, enabling a wide range of scheduled and charter flights. In addition to passenger movement, the airport handles air freight and mail, supporting regional commerce and logistics. The airport’s operations are governed by federal aviation regulations and overseen by the City of Phoenix Aviation Department.

Phoenix Sky Harbor ranks among the busiest airports in the United States, accommodating a substantial volume of travelers each year and contributing significantly to the regional economy. Its distinguishing attributes include a robust international customs and border protection facility, extensive runway capacity that accommodates large aircraft, and a role as a major connecting hub for several major carriers. The airport’s infrastructure is continuously modernized to meet evolving security and passenger service standards. Ownership resides with the City of Phoenix, and its day-to-day management is carried out by the Aviation Department, a municipal agency. In October 2022, the airport experienced a distributed denial‑of‑service attack conducted by the pro‑Russian hacktivist group KillNet, which temporarily disrupted online services such as flight information and booking platforms while leaving actual flight operations unaffected. This incident highlighted the growing cyber‑threat landscape facing critical transportation infrastructure.
