Cheap National Car Rentals at San Francisco International Airport, SFO

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

If you're traveling with pets, confirm the rental company's pet policy before booking. Some companies allow pets but may have specific fees or restrictions, so it’s best to clarify in advance.

Ask if there are extra charges for picking up at the airport versus off-site locations.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Take a moment to familiarize yourself with the vehicle's controls and features before driving off. Knowing how to operate essentials like headlights, wipers, and navigation systems can enhance safety and convenience.

To save on refueling costs when departing from Airport, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.

Refer to your booking confirmation for detailed pickup instructions and required documents.
