Park in the designated after-hours area, place the keys in the secure drop-box, and take the airport shuttle.

## What to know

For customers returning vehicles outside of our standard counter operating hours (6:00 AM to 12:00 AM), we provide a seamless 24/7 drop-off protocol. First, drive to the SeaTac Rental Car Facility located off 185th Street. Follow the specific signage for 'After-Hours Returns' to reach the designated parking zone. Once you have parked the vehicle, ensure it is locked and all personal belongings are removed. You must place your keys in the provided key envelope and deposit them into the secure, weathered key drop-box located at the main entrance of the rental office building. After dropping the keys, proceed to the nearest shuttle bus stop. Airport shuttles operate every 15 to 20 minutes to transport you to the main terminal. Please note that your final vehicle inspection and billing will be processed by our team during the next available business day, and you will receive a digital email receipt within 24 hours of your drop-off. This protocol ensures your return is recorded accurately at the exact time of arrival, regardless of your flight schedule.
