How do I distinguish between the North and South Terminal shuttles when returning to SeaTac Airport from the Rental Car Facility?

Upon arriving at the Rental Car Facility, travelers heading back to SeaTac Airport need to navigate to Level 5 to catch their return shuttle. It's crucial to identify the correct shuttle to ensure you reach the right terminal. The Rental Car Facility operates two distinct shuttle services: one for the North Terminal and one for the South Terminal. The shuttles are clearly labeled, and the signage is prominently displayed. Travelers should check the shuttle signs or ask the staff to confirm which shuttle is headed to their desired terminal. The shuttle frequency is approximately every 6-10 minutes, with a travel time of around 5-7 minutes to the terminals. The North Terminal shuttle typically services airlines such as Alaska, Delta, and American Airlines, while the South Terminal shuttle services airlines like Southwest and Frontier. To avoid confusion, it's recommended to double-check with the rental car staff or the shuttle driver if you're unsure about the terminal or shuttle. By doing so, you can ensure a smooth and hassle-free return journey to the correct terminal at SeaTac Airport.
