Phoenix Sky Harbor International Airport is the main airport in Phoenix and the Valley of the Sun, Arizona. While PHX is one of the busiest airports, it is quite easy to navigate when you have knowledge about its two active terminals and the free PHX Sky Train.
Phoenix Sky Harbor has two operational terminals, Terminal 3 and Terminal 4. Terminal 2 was shut down in February 2020, thus explaining the non-consecutive numbers for the terminals. The PHX Sky Train connects both terminals to the airport parking, rental car center, and Valley Metro Rail.
Use the below Phoenix Sky Harbor International Airport map guide to find your airline, gates, security check-in, baggage claim, parking, and transportation options.
PHX Airport Map Overview
The best way to understand Phoenix Sky Harbor is to see it as an east-to-west transportation hub:
The 44th Street and Washington station links the airport to Valley Metro Rail, which provides transport to Phoenix, Tempe, and Mesa. The 24th Street station caters to west-side airport parking and accesses Buckeye Road. PHX also has an official interactive map of the airport that gives directions to various points. Visitors can use it to locate gates, dining places, shopping centers, restrooms, lounges, charging facilities, ATMs, and other services.
Terminal 3 Map: Gates E and F
Terminal 3, commonly referred to as John S. McCain III Terminal, is the smaller of PHX’s two terminals. It holds the E and F gate areas and has only one security checkpoint.

Tips for Moving from One Terminal to Another
Transitioning from one terminal to another at Phoenix Sky Harbor International Airport (PHX) is relatively easy, particularly due to the PHX Sky Train that operates around the clock. Note, however, that it is advisable to plan your journey ahead since there may be additional time needed for security and baggage handling if a passenger transitions between two terminals.
Key tips to consider include the following:
- Using the PHX Sky Train: This free rail system links Terminal 3 and Terminal 4 and runs 24/7. Passengers with wheelchairs and mobility problems can use this system.
- Frequency of operation: The system generally runs fairly frequently throughout the day. However, trains may run less frequently from 10 pm to 5 am due to scheduled maintenance work.
- Changing terminals: If a passenger’s next flight is from another terminal, the passenger will have to exit the secure area, retrieve luggage if necessary, use the Sky Train, and re-enter the secure area.
- Contact your airline: There may be variations in procedures depending on one’s itinerary. Note especially if the flights were booked separately or with different airlines.
