## At a glance

Shuttles are divided into North and South loops based on the specific terminal and rental location to ensure correct matching.

## What to know

At Seattle Seattle-Tacoma International Airport, the Rental Car Facility operates via two distinct shuttle circuits designated as the North Loop and the South Loop to maintain efficient passenger flow. Travelers must identify their terminal's designated loop to board the correct shuttle. The North Loop shuttle primarily serves Terminals A and B, as well as the rental agencies located on the northern end of the facility. Conversely, the South Loop shuttle is designated for Terminal C and the rental agencies situated on the southern side. Both shuttles typically operate every 5 to 15 minutes during peak travel hours to minimize wait times. When returning a vehicle, passengers should follow the clear signage within the Rental Car Facility to find the specific loading bay corresponding to their terminal's loop. Boarding the wrong loop can result in significant delays, as the buses do not stop at terminals on the opposite side of the complex. It is highly recommended to check the digital displays at the shuttle bay to confirm the next incoming North or South loop vehicle for your specific terminal location.
