This busy holiday travel season Waymo One riders can now get picked up or dropped off curbside at Phoenix Sky Harbor Terminals 3 and 4.

The terminal service is currently available to select riders from 10 p.m. to 6 a.m., as Waymo continues testing the complex driving environment. In the coming months, the company intends to offer these pickup locations to all riders with the goal to expand to 24/7 service, according to a press release.

These new options are in addition to pick-up locations at Sky Harbor’s 24th and 44th Street SkyTrain Stations, the latter of which opened this time last year.

“Last year, we partnered with Waymo to become the first airport in the world to offer travelers the ability to take an autonomous vehicle to the airport,” Chad Makovsky, Sky Harbor aviation director, stated in the press release. “This partnership has allowed us to develop confidence in the technology, and we’re excited to take the next step and safely expand this innovative service to our terminal curbs.”
