Cheap Global Rent A Car Car Rentals at Cologne Airport, CGN

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

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

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 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.

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.

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.

Before traveling, familiarize yourself with local driving laws and regulations. This can help you avoid fines and ensure a safe driving experience.

Many companies offer apps with live updates and alerts regarding your vehicle pickup.
