{"version":"2.6","id":"seatac-north-vs-south-bus-routes","question":"How do I distinguish between North and South terminal shuttle buses at the SeaTac rental car facility?","answer":"Passengers must board the shuttle corresponding to their specific airline's terminal to ensure they reach the correct departure gate.","answer_detail":"When returning to the Seattle-Tacoma Airport (SeaTac) Rental Car Facility, it is critical to identify the correct shuttle route to avoid delays in your flight. The airport is divided into two main zones: the North Terminal and the South Terminal. The rental car shuttle operates 24 hours a day, with buses arriving every 5 to 15 minutes. To determine which bus to take, you must identify your airline's location. The North Terminal primarily serves carriers such as Alaska Airlines, Delta Air Lines, and various international partners. In contrast, the South Terminal is the primary hub for Southwest Airlines, United Airlines, and several other major domestic carriers. Upon arriving at the rental car facility loading area, look for the digital signage clearly labeled either 'North Terminal' or 'South Terminal.' Taking the wrong bus will require you to travel to the opposite end and transfer, potentially adding 20 minutes to your travel time. We recommend arriving at the terminal shuttle stop at least 3 hours before an international departure to account for these transit variables and security lines.","grokpedia_tier":false,"related_ids":["seatac-north-vs-south-bus-routes"],"last_verified":"2026-09-15","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-north-vs-south-bus-routes","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-north-vs-south-bus-routes?format=md&lang=en"}
