Phoenix Sky Harbor International Airport (PHX) is a large and modern aviation hub with a well-thought-out structure that facilitates passenger navigation. Currently, two passenger terminals function at the airport: Terminal 3 and Terminal 4. The previously existing Terminal 2 was closed in 2020, and all its airlines moved to more modern facilities.
Terminal 3 (John S. McCain III Terminal) is a modern and compact terminal serving flights for several major airlines, such as Delta, Frontier, JetBlue, and United. It consists of two concourses — F and E. The space is organised very logically: check-in counters and security checkpoints are on one level, while boarding gates are on another. There are many cafes, restaurants, and shops here, allowing you to comfortably pass the time while waiting for your flight.
Terminal 4 (Barry M. Goldwater Terminal) is the largest and busiest terminal of the airport. It serves as the main hub for American Airlines and Southwest Airlines. Additionally, all international flights are handled in Terminal 4. The terminal has eight concourses (A, B, C, D on the south side and A, B, C, D on the north), making it significantly larger than Terminal 3. It features the widest selection of shops, restaurants, and premium lounges.
To move between terminals, as well as to access parking lots and the Valley Metro Rail station, the free automated PHX Sky Train® is used. It runs around the clock with short intervals, making trips between Terminal 3, Terminal 4, and transport hubs fast and convenient. Walking between the terminals is not provided for.
Check-in and security procedures in both terminals are organised efficiently, but the time to complete them can vary greatly depending on the season, day of the week, and time of day. It is recommended to arrive at the airport at least 2 hours before a domestic flight departure and 3 hours before an international one. For quick navigation, follow the signs and use the interactive maps available throughout the airport, and always rely on the PHX Sky Train® for moving between buildings.
