Phoenix Sky Harbor Airport Terminal

Phoenix Sky Harbor International Airport (PHX) is Arizona’s busiest airport and currently operates two terminals: Terminal 3 and Terminal 4. Whether you’re flying for business, heading out on vacation, or picking up arriving passengers, knowing your departure terminal before you arrive can help you avoid unnecessary delays and make navigation easier. It can also help you figure out airport parking, how to get between terminal facilities, and find the right pickup and drop-off locations.

Phoenix Sky Harbor International Airport is nicknamed America’s Friendliest Airport and features two terminals. Terminal 3 (sometimes called the John S. McCain III Terminal) sits on the airport’s west side, while Terminal 4 (the Barry M. Goldwater Terminal) sits on the east side. Older terminals (Terminal 1 and Terminal 2) have been retired as part of the airport’s long-term modernization efforts. The terminal layout is simpler compared to other major U.S. airports, making it easier for first-time visitors to navigate.

Both terminals offer modern facilities, security checkpoints, dining, shopping, charging stations, and easy access to ground transportation. The terminals are connected by the free PHX Sky Train, allowing travelers to move easily between terminals.

Terminal 3 consists of 27 gates and primarily serves domestic carriers. Terminal 3 underwent a major renovation in recent years and now offers a bright, modern environment with expanded dining, shopping, and passenger amenities. Construction of a new north concourse at Terminal 3 is currently underway. The new concourse will add approximately 173,000 square feet of space for six new passenger gates.

Terminal 4 is the largest terminal at Phoenix Sky Harbor and handles the majority of passenger traffic. Phoenix Sky Harbor Terminal 4 features 92 gates and serves both domestic and international travelers, handling roughly 75% of the airport’s traffic. Since it accommodates more airlines and flights than Terminal 3, Terminal 4 experiences higher passenger volumes throughout the day. The terminal serves as American Airlines’ major western hub and a key Southwest Airlines base.

The construction of the unnamed terminal will mark the first new terminal at PHX Airport since Terminal 4 opened in 1990. It is expected to be completed in 2033 and will be built on the west side of the airport between Terminal 3 and Taxiway U.

The two terminals are located in separate buildings. One of the biggest advantages of Phoenix Sky Harbor International Airport is how easy it is to travel between terminals. Unlike airports that require lengthy shuttle bus rides, PHX uses the PHX Sky Train, a free automated train system that connects the Rental Car Center, the 24th Street Station, Terminal 3, Terminal 4, East Economy Parking, and Valley Metro Rail in just a few minutes.

The train operates frequently throughout the day, making it the quickest and most convenient way to move around the airport. If you accidentally arrive at the wrong terminal or need to reach the Rental Car Center after your flight, simply follow the clearly marked signs to the nearest Sky Train station.

Both Terminal 3 and Terminal 4 have TSA security checkpoints serving departing passengers. Wait times vary throughout the day depending on passenger volume, airline schedules, and seasonal travel demand.

No matter which terminal you’re flying from, arriving at the correct parking facility can make your travel day much smoother. Before reserving a parking space, verify your airline’s terminal and review the shuttle information if you’re using an offsite parking provider.

A little preparation goes a long way toward creating a stress-free airport experience. Before heading to your terminal:
