## What to know

The rental car facility at SeaTac International Airport operates with extended hours to accommodate travelers, but please be aware of the daily overnight closure gap. Specifically, the physical service counters are closed between 1:00 AM and 5:00 AM daily. If you need to return your vehicle during this 4-hour window, you cannot check in with a rental agent in person. To complete an off-hours return, drive the vehicle to the designated rental return area. Once parked, you must locate the secure key drop box, which is typically situated near the main rental office entrance. It is mandatory to remove the vehicle keys from the ignition and place them inside the drop box. After dropping the keys, we recommend taking a photograph of the vehicle's fuel level and exterior condition for your records. Your return will be processed by the next available agent once the counter reopens at 5:00 AM. Ensure the fuel tank is at the level specified in your rental agreement to avoid additional refueling surcharges during the overnight period.
