PHX Sky Train

[5] The PHX Sky Train replaced shuttle buses for transit within the airport property.

It links Terminal 4, the East Economy Parking lot, and the 44th Street/Washington station of the Valley Metro Rail.

[2] The guideway runs in a new underpass (below the Union Pacific railroad), past the jet-fuel tank farm, and alongside 44th Street.

[8] Phase 2 opened on December 20, 2022, and extended the Sky Train west from Terminal 3 to the Rental Car Center.

[10][12] Both the new terminal and new ground transportation center are unfunded and included in the airport's 20-year Comprehensive Asset Management Plan.

Select airlines also offer kiosks to print boarding passes at the 44th Street/Washington and East Economy Parking stations.

[5] Three months after opening, the PHX Sky Train carried about 70,000 people per week, over 40% higher than the design estimates of about 48,000.

[citation needed] The average speed of the trains was forecasted to be 23 miles per hour (37 km/h), with trainsets capable of reaching 38 miles per hour (61 km/h), making the journey time from the 44th Street to Terminal 4 five minutes, plus an additional two minutes to reach Terminal 3.
