Cheap National Car Hire Deals at San Francisco International Airport, SFO

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

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 plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

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

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

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

If returning your rental at the airport, be aware of the parking policies and any fees involved.
