Cheap United Rentacar Car Hire Deals at Porto Airport, OPO

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

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.

Take a moment to familiarize yourself with the vehicle's controls and features before driving off. Knowing how to operate essentials like headlights, wipers, and navigation systems can enhance safety and convenience.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Some rental agreements come with mileage limits, while others offer unlimited mileage. Make sure to review the mileage policy to avoid unexpected fees.

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

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