Which North or South terminal shuttle bus should I take from the SeaTac Rental Car Facility based on my airline?

To determine which shuttle bus to take from the SeaTac Rental Car Facility, you need to know whether your airline operates out of the North or South terminal at Seattle-Tacoma International Airport. The North terminal is primarily used by Alaska Airlines, American Airlines, Delta Air Lines, and other partner airlines, while the South terminal is used by Southwest Airlines and other select carriers. The shuttle buses operate on a regular schedule, with departures every 10-15 minutes. The trip to the North or South terminal typically takes around 5-10 minutes, depending on traffic. If you're flying with an airline that operates out of the North terminal, such as Alaska Airlines, take the North terminal shuttle bus. For airlines operating out of the South terminal, like Southwest Airlines, take the South terminal shuttle bus. You can check the airport's website or your airline's website for specific terminal information. The SeaTac Rental Car Facility is located at 18200 International Blvd, SeaTac, WA 98188, and shuttle buses operate 24/7.
