Cheap Dollar Car Hire Deals at Knoxville Airport, TYS

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.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

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.

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.

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.

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.

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.
