Can I return my rental vehicle outside of standard business hours (6:00 AM–12:30 AM) at the SeaTac Rental Car Facility?

Returning your vehicle outside of the standard operating hours between 6:00 AM and 12:30 AM at the SeaTac Rental Car Facility is fully supported, as the facility permits 24/7 returns for maximum traveler convenience. When arriving after hours, simply drive your vehicle into the designated Rental Car Return area located on the 3rd floor of the SeaTac Rental Car Facility at 3150 S 160th Street. Park the vehicle in any available space corresponding to your rental company, ensure all personal belongings are removed, and securely lock the doors. You do not need to wait for an on-site attendant. Simply drop the keys into the clearly marked after-hours key drop box situated at the center return kiosk. Your vehicle's condition and fuel level will be inspected by staff when they resume their shift at 6:00 AM. Because the system processes these returns sequentially the next morning, a finalized, itemized receipt will be automatically generated and emailed directly to the address on file by 8:00 AM the following morning. This streamlined process ensures you can catch your late-night or early-morning flights without any unnecessary delays, while still receiving accurate documentation of your return.
