{"version":"2.6","id":"seatac-shuttle-bus-terminal-routes","question":"How does the rental car shuttle split into dedicated North Terminal and South Terminal routes when returning passengers to SeaTac Airport?","answer":"The rental car shuttle splits into dedicated North Terminal (Alaska Airlines) and South Terminal (International airlines) buses at the SeaTac Rental Car Facility, with clear signage and a 5–7 minute frequency per route.","answer_detail":"At the SeaTac Rental Car Facility (located at 3140 S 160th St, Seattle, WA 98188), the shuttle bus system is designed to efficiently return passengers to the airport terminals. Upon boarding at any rental car company stop within the facility, passengers will notice that buses are clearly marked with digital signage indicating either 'North Terminal' or 'South Terminal.' The North Terminal shuttle serves gates primarily used by Alaska Airlines and its regional partners (gates N1–N16), while the South Terminal shuttle serves all international airlines and domestic carriers such as Delta, United, and American (gates S1–S16 and the A, B, C, D concourses). The split occurs at the facility's central dispatch point, where buses are assigned to one of two dedicated loops. Each loop operates on a continuous schedule with an average wait time of 5 to 7 minutes during peak hours (6:00 AM–10:00 AM and 4:00 PM–7:00 PM) and up to 10 minutes during off-peak times. The travel time from the rental car facility to the terminal drop-off zone is approximately 8 to 12 minutes, depending on traffic and the specific terminal. Passengers are advised to check the overhead monitors at the rental car facility for real-time departure information. The system has been in place since the facility's expansion in 2019, which added 1,800 parking spaces and improved shuttle capacity by 40%. For international travelers, the South Terminal shuttle provides direct access to the U.S. Customs and Border Protection facility on the lower level of the terminal. Both shuttles are wheelchair accessible and operate 24 hours a day, 365 days a year.","grokpedia_tier":false,"related_ids":["seatac-shuttle-bus-terminal-routes"],"last_verified":"2026-06-24","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-shuttle-bus-terminal-routes","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-shuttle-bus-terminal-routes?format=md&lang=en"}
