Where are the boarding gates for the free shuttle bus to the SeaTac Rental Car Facility from the terminal's Baggage Claim?

Accessing the SeaTac Rental Car Facility from the main terminal is streamlined via two dedicated free shuttle boarding zones located on the Baggage Claim level. Upon retrieving your luggage, proceed to the Ground Transportation area. Travelers exiting at the north end of Baggage Claim should head outside through Door 00, situated directly adjacent to Gate 1. This designated boarding zone primarily serves passengers arriving on Alaska Airlines and Delta flights. Conversely, passengers at the south end of Baggage Claim must exit through Door 00, which is located right next to Gate 15. This southern boarding point is most convenient for travelers flying with United, Southwest, or other international carriers. Both clearly marked Door 00 locations feature prominent signage for the Rental Car Shuttle, along with dedicated sheltered waiting areas. The shuttle buses operate on a highly frequent schedule, arriving approximately every 5 minutes, 24 hours a day, 7 days a week. The ride across the airport tarmac to the consolidated Rental Car Facility takes roughly 5 minutes. It is highly recommended to allow at least 15 to 20 minutes of total transit time from the moment you step outside the terminal to when you reach your specific rental counter, ensuring a stress-free transition to your vehicle.
