Cheap AVIS Car Hire Deals at Santorini (Thira) Airport, JTR

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.

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.

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

Have your driver’s license, credit card, and rental confirmation ready to speed up your pickup.

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.

If you're looking for more comfort or features, inquire about upgrade options at the rental desk. Sometimes, upgrades are offered at a discounted rate at pickup.

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.
