{"version":"2.6","id":"seatac-airline-dependent-shuttle-return","question":"How do I know which shuttle bus to take when returning to SeaTac Airport from the Rental Car Facility?","answer":"You must board either the North or South terminal shuttle bus based strictly on your departing airline.","answer_detail":"When returning your vehicle at the SeaTac Rental Car Facility, it is crucial to select the correct airline-specific shuttle bus for your return trip to the main terminal. The facility operates two distinct shuttle routes: one serving the North Terminal and another serving the South Terminal. Passengers must strictly board the bus that corresponds to their departing airline to avoid lengthy walking distances between terminals or missing their flights. For instance, if you are flying with Alaska Airlines, Delta, or United, you must board the South Terminal shuttle. Conversely, if your itinerary includes airlines such as American Airlines, Southwest, or British Airways, you are required to take the North Terminal shuttle. The shuttle buses depart approximately every 4 to 6 minutes from the designated transit center on the ground floor of the Rental Car Facility. The ride itself takes about 5 to 8 minutes depending on traffic within the airport perimeter. Clear digital signage and color-coded markers (typically Blue for South and Green for North) are displayed at each boarding bay to guide travelers. Always verify the electronic screens on the bus before boarding, as airline gate assignments occasionally change. Taking the wrong shuttle can add over 20 minutes of walking time via the terminal train, so paying close attention to these airline-specific designations is essential for a smooth return process.","grokpedia_tier":false,"related_ids":["seatac-airline-dependent-shuttle-return"],"last_verified":"2026-06-28","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-airline-dependent-shuttle-return","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-airline-dependent-shuttle-return?format=md&lang=en"}
