Which shuttle bus should I take from the SeaTac Rental Car Facility to the airport terminals based on my airline?

When returning to SeaTac Airport from the Rental Car Facility, it's essential to take the correct shuttle bus to ensure you arrive at the right terminal. The airport is divided into North and South terminals, with different airlines operating from each. To avoid confusion, check your airline's terminal location before heading to the airport. The shuttle buses operate on a regular schedule, with departures every 10-15 minutes. The journey takes approximately 10-15 minutes, depending on traffic. For example, Alaska Airlines, Delta Air Lines, and American Airlines operate from the North terminal, while Southwest Airlines and United Airlines operate from the South terminal. If you're flying with an airline located in the North terminal, take the North terminal shuttle bus, which departs from the designated North terminal shuttle bus stop at the Rental Car Facility. Conversely, if your airline is in the South terminal, take the South terminal shuttle bus. You can check the airport's website or your airline's website for the most up-to-date information on terminal locations and shuttle bus schedules. The Rental Car Facility is located at 18200 International Blvd, SeaTac, WA 98188, and the shuttle buses operate 24/7.
