## What to know

To ensure a seamless return process at the SeaTac Rental Car Facility, drivers must choose between two primary navigation routes based on their location. If you are located to the north of the airport, utilize International Blvd / SR 99 South. Continue south for approximately 2.5 miles until you see the dedicated signage for the 'Rental Car Center.' This route is often the most efficient for those arriving from downtown Seattle, as it avoids internal terminal traffic congestion. Alternatively, if you are already within the airport perimeter or southern approach, follow the green signs marked 'Airport Access Road.' This local route leads you directly to the consolidated car rental facility. Once you arrive at the facility, follow the marked lanes for vehicle check-in. Please note that the facility operates 24 hours a day, but we recommend arriving at least 60 minutes before your scheduled flight to account for traffic. Ensure your vehicle is fueled according to the rental agreement terms to avoid additional refueling charges during the return process.
