How do I return a vehicle during late-night or after-hours at the SeaTac Rental Car Facility, and what is the shuttle frequency?

Detailed answer

The SeaTac Rental Car Facility (RCF), located at 3150 South 160th Street, SeaTac, WA 98188, operates 24 hours a day, 7 days a week, accommodating late-night and early morning vehicle returns for all major rental agencies. To return your vehicle during after-hours, drive directly to the facility via the dedicated rental car return lanes and follow the overhead signage for your specific rental company. Proceed to the designated return area where automated gate systems or on-site overnight attendants will process your vehicle entry. Ensure you lock the car, note the final mileage, fuel level, and place the keys in the secure key drop-box if your specific agency's counter is unattended. After completing the vehicle return, proceed to the central shuttle bus loading zone located on Floor 5 of the facility. During off-peak hours, specifically between 1:00 AM and 5:00 AM, the complimentary airport shuttle buses run at a frequency of every 15 to 20 minutes to transport passengers back to the main terminal's baggage claim level. Please allow at least 30 to 45 minutes for the entire return and shuttle transfer process before your flight's scheduled boarding time.
