Which terminal shuttle bus should I take from SeaTac Airport to the Rental Car Facility, and how do I get back?

Detailed answer

To travel between SeaTac Airport and the Rental Car Facility, use the dedicated shuttle buses. After collecting your baggage from Carousel #1 or #15, proceed to the designated shuttle bus stops outside the baggage claim area. Airlines arriving at the North Terminal include Alaska, American Airlines, Delta, and more. For these, take the North Terminal shuttle bus. Airlines arriving at the South Terminal include Air Canada, British Airways, Lufthansa, and others; take the South Terminal shuttle bus. The shuttle buses operate at regular intervals, typically every 10-15 minutes, with a travel time of approximately 5-7 minutes to the Rental Car Facility, located at 18200 International Blvd. When returning to SeaTac Airport, follow the same terminal designation rules for drop-off: North Terminal airlines at the North lot, and South Terminal airlines at the South lot. Be sure to check the airline's terminal information before your trip to ensure you board the correct shuttle.
