Check the operating hours of your rental company, as some may have limited hours at airports.

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.

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

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.

Opt for a pickup location near your arrival terminal to minimize time spent locating your vehicle.

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.

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.

Allow for possible delays at the rental desk, particularly during busy travel times.
