Customers must use the key drop box; a $45 surcharge applies for returns made after 09:00 AM.

## What to know

For customers returning vehicles to the SeaTac rental car facility outside of standard operating hours, a specific protocol must be followed. If you return your vehicle after the office closes at 09:00 AM, staff will not be available to assist you personally. In these instances, you must park the vehicle in the designated after-hours return zone and place the keys inside the secure key drop box located at the main rental counter. Please be advised that a flat $45 after-hours surcharge is applied to all returns processed during this window. Furthermore, it is critical to note that late-night shuttle services are not available after operational hours; travelers must arrange their own private transportation or ride-share to reach the terminal. Regarding liability, the renter remains fully responsible for the vehicle and its contents until a staff member officially processes the return when the office opens at 09:00 AM the following business day. Ensure the vehicle is fueled to the original level and cleaned before drop-off to avoid additional cleaning charges during the morning inspection process.
