## What to know

When returning your rental vehicle to the SeaTac Rental Car Facility outside of operating hours, please follow these steps: Pull your vehicle completely forward on the designated National floor, which is typically open 24/7 for drop-offs. Ensure you are on the correct floor as indicated by the rental agreement and facility signage. Once in position, place the vehicle keys in the secure drop box provided. Do not lock the keys inside the vehicle. The secure drop box is designed to receive the keys safely. After depositing the keys, you have completed the after-hours return process. The facility operates with a 24-hour return policy, and the average processing time for returned vehicles is under 30 minutes once the facility staff processes the drop box contents during their next business hour, typically starting at 8:00 AM. For rentals returned after 11:59 PM, the return date will be considered as the next business day. The facility's address is 17801 International Blvd, SeaTac, WA 98188.
