In response to high demand, San Diego International Airport has relocated its cell-phone waiting lot to add 47 parking spaces. The move brings the total number of spaces to nearly 100. The expanded cell-phone lot has been relocated east of the Commuter Terminal on Harbor Drive, and is now accessible through a traffic light at Rent-a-Car Access Road. Airport officials said drivers can park for free in the cell-phone lot for up to 60 minutes while they wait for the call that their loved ones have landed in San Diego. The cell-phone lot has been a popular benefit for drivers accessing the airport, and the additional spaces will allow more people to access the lot, especially at peak times. The cell-phone lot is available for use 24 hours a day, according to airport officials. As the cell-phone waiting lot is relocated, SAN Park Harbor Drive will also be relocating its spaces north of its current location to allow for remediation of the existing parking lot. The interim parking opened for airport customers June 14.  The new parking lot will utilize the same entrance/exit at Harbor Drive and Rent-a-Car Access Road. Airport officials said travelers must adhere to the official walkways when walking to and from the interim parking lot to the terminals because the surrounding area is an active construction site. Posted signs will offer easy pedestrian access to the terminals.
