Phoenix Sky Harbor International Airport (PHX)

Phoenix Sky Harbor International Airport (PHX) operates through three main passenger terminals: Terminal 2, Terminal 3, and Terminal 4, all seamlessly connected airside via an enclosed, air-conditioned walkway system that protects travelers from Arizona's extreme desert heat. Terminal 4 is the airport's largest and most modern facility, serving as the primary hub for American Airlines and handling the majority of international flights. Terminal 3 accommodates Southwest Airlines and several other domestic carriers, while Terminal 2 serves various airlines including Delta Air Lines, United Airlines, and other domestic and limited international operations. The terminal connection system allows passengers to move freely between all three terminals without exiting security, with walking times typically ranging from 8-15 minutes depending on the origin and destination gates. The climate-controlled walkways feature moving sidewalks and are designed to provide relief from Phoenix's intense summer temperatures that can exceed 115°F (46°C). Each terminal maintains its own security checkpoints with TSA PreCheck and CLEAR lanes available, though passengers connecting between terminals can bypass additional security screening. International passengers arrive primarily at Terminal 4, which houses comprehensive immigration and customs facilities including Global Entry kiosks and duty-free shopping areas. PHX's amenities reflect the Southwestern culture and Arizona's distinctive character, featuring numerous dining options that highlight local and regional cuisine, including authentic Mexican and Native American-inspired restaurants, steakhouses, and craft breweries showcasing Arizona-made beers. The airport's shopping areas offer distinctive Southwestern merchandise, Native American art, and desert-themed souvenirs alongside standard retail and duty-free options. Airline lounges include American Airlines' Admirals Clubs in Terminal 4, Delta Sky Clubs, and United Clubs, with many offering panoramic views of the dramatic desert mountain landscape. Ground transportation is extensive, with rental car facilities accessible via shuttle, the PHX Sky Train connecting to the Rental Car Center, light rail service to downtown Phoenix and Tempe, and comprehensive taxi, ride-sharing, and airport shuttle services.
