Phoenix airport Sky Train to the Rental Car Center opens Tuesday. Here's what we know

Renting cars at Phoenix Sky Harbor International Airport is about to get a lot more convenient for travelers, right in time for the holidays.

Starting Tuesday, Dec. 20, the airport's PHX Sky Train will launch its extended service from Terminals 3 and 4 to the Rental Car Center for the first time.

The airport's long-awaited Stage 2 extension was completed recently following extensive safety tests and is now ready to transport passengers. Here's what we know ahead of its debut to the public.

How much longer is the PHX Sky Train route?

The Stage 2 extension added 2.5 miles of track to the existing Sky Train route.

From end to end, the mileage between the 44th Street/Washington PHX Sky Train Station and the Rental Car Center is 5 miles, or about 13 minutes.

How much did it cost?

Stage 2 of the PHX Sky Train cost $745 million, according to airport staff. The work is among $1.7 billion worth of upgrades the airport planned over a five-year period in a comprehensive asset management plan approved in 2019.

What problems does the Sky Train extension solve?

Most critically, the Sky Train's connection to the Rental Car Center will be able to move larger numbers of passengers quicker and more efficiently than the current shuttle bus system.

People board the PHX Sky Train at the 24th Street Station for its first trip to the rental car center during media day at Phoenix Sky Harbor International Airport on Dec. 19, 2022, in Phoenix, Ariz. Stage 2 of the PHX Sky Train extends the train's route to the Rental Car Center and begins transporting airport travelers on Dec. 20, 2022.

Trains will arrive every three to five minutes. Shuttle buses, in contrast, arrive every seven to 13 minutes depending on traffic — though some travelers reported horror stories of waiting far longer during peak travel periods.

Replacing the buses with the Sky Train will also reduce traffic along Sky Harbor Boulevard.

The route extension also includes a new Sky Train Station at 24th Street, accessible from Buckeye Road and Copperhead Drive, which will add about 1,600 economy parking spaces and about 22 electric vehicle charging stations. Like the station at 44th and Washington streets, people can use it to pick up and drop off passengers to reduce traffic jams on the terminal roadways.
