Cheap Keddy by Europcar Car Rentals at Dusseldorf International Airport, DUS

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.

Select a pickup location that is convenient for you. Some rental companies offer locations within the airport for quick access, while others may require shuttle transportation.

Most rental companies will require a credit card for the deposit, which is typically frozen in your account. Make sure to inquire about the specific deposit amount and the policy for releasing the freeze.

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

Many companies offer apps with live updates and alerts regarding your vehicle pickup.

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

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.

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.
