When returning from the SeaTac Rental Car Facility to the terminal, how do I determine which dedicated North or South terminal shuttle bus to board based on my airline?

When returning from the SeaTac Rental Car Facility to Seattle-Tacoma International Airport terminals, it's essential to board the correct dedicated shuttle bus to ensure you arrive at the right terminal for your airline. The facility is connected to both the North and South terminals via shuttle services. To determine which shuttle to take, check the designated airline stops at the Rental Car Facility. The shuttle buses are clearly marked as 'North Terminal' or 'South Terminal. ' Most major airlines operating out of Seattle-Tacoma International Airport are assigned to either the North or South terminal. For instance, Alaska Airlines and Delta Air Lines operate out of both terminals, but specific flights may be assigned to one terminal. The shuttle service operates approximately every 10-15 minutes, and the journey takes around 5-10 minutes depending on traffic. The Rental Car Facility is located at 18200 International Blvd, SeaTac, WA 98188. It's recommended to check the airport's website or your airline's information for the most up-to-date terminal assignments to plan your return journey accordingly.
