How do I navigate the Hertz Ultimate Choice zones and upgrade my vehicle at the SeaTac Rental Car Facility?

Upon arriving at Seattle-Tacoma International Airport (SeaTac), proceed to the Ground Transportation level at baggage claim and take the blue rental car shuttle buses, which arrive every 3 to 5 minutes. The shuttle will transport you to the main Rental Car Facility located at 3150 S 160th Street. Once inside the Hertz lobby, proceed to the Hertz Ultimate Choice area. Here, a large digital board will display your name alongside your assigned zone category, such as Zone 1 for standard economy cars or Zone 3 for full-size sedans and SUVs. Instead of waiting for a pre-assigned vehicle, you simply walk to your designated zone, select the specific car you prefer from the available inventory parked there, and take the keys from the ignition or the dashboard. If you wish to upgrade to a premium vehicle—like moving from a mid-size sedan in Zone 2 to a luxury SUV in Zone 5—you can select a car from a higher-tier zone. When you arrive at the exit gate, the Hertz attendant will process the upgrade and charge the daily rate difference, which typically starts around $25 per day depending on the vehicle class. This streamlined process eliminates the need to wait at a counter and allows you to get on the road much faster.
