{"version":"2.6","id":"seatac-return-level-and-after-hours-drop-box","question":"How do I navigate the rental car return at SeaTac and use the after-hours drop box?","answer":"Return to Level 3 for Sixt, Level 5 for shuttles, or use the designated drop box for off-hours returns.","answer_detail":"Navigating the return process at the SeaTac Airport Rental Car Facility requires attention to specific floor levels to ensure a smooth transition. If you are returning a vehicle to Sixt, you must drive specifically to Level 3 of the parking structure. For all other rental agencies that require a shuttle bus to get back to the airport terminals, you should proceed to Level 5, where the shuttles typically run every 10 to 15 minutes during peak hours. If you are returning your vehicle after business hours, you must utilize the secure after-hours drop box. This key drop box is conveniently located on Level 3 near the Sixt rental counter area. Before leaving the vehicle, ensure it is parked in a designated stall, locked, and the keys are clearly placed in the drop box. It is highly recommended to take photos of the car's fuel level and exterior condition upon return to avoid any potential billing disputes during the final billing cycle or overnight inspection process.","grokpedia_tier":false,"related_ids":["seatac-return-level-and-after-hours-drop-box"],"last_verified":"2026-09-12","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-return-level-and-after-hours-drop-box","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-return-level-and-after-hours-drop-box?format=md&lang=en"}
