Cheap Keddy by Europcar Car Rentals at Lille Airport, LIL

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.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

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

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.

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.

Determine if your rental provider has an airport desk or if you’ll need to take a shuttle to reach them.

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

Always keep your rental agreement, identification, and insurance information easily accessible during your rental period. This can help resolve any issues quickly.
