## What to know

Navigating car rentals at Seattle-Tacoma International Airport (SEA) requires understanding the distinction between the Rental Car Facility (RCF) and off-site providers. On-site major brands—such as Hertz, Enterprise, and Avis—are located directly within the consolidated RCF terminal. After collecting baggage, travelers simply follow the signs to the off-terminal pedestrian concourse to reach the counters on foot. This process typically takes 5 to 10 minutes. In contrast, off-site independent agencies like Fox, Sixt, or peer-to-peer platforms like Turo are located miles away from the terminal. To access these, travelers must travel to the Ground Transportation Center (GTC), where they must wait for a dedicated shuttle. These shuttles typically run every 15 to 30 minutes, and the transit time can add an additional 20 to 45 minutes to the pickup process. While off-site providers often offer lower rates—sometimes 20% to 30% cheaper than RCF brands—the logistical overhead of shuttle transfers makes them less convenient for travelers on tight flight schedules.
