Cheap National Car Hire Deals at Sao Paulo Congonhas Airport, CGH

Before returning the vehicle, clarify the return procedures with the rental company. Knowing where to drop off the car and any required inspections can streamline the process.

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.

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.

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

Inspect the vehicle for pre-existing damage and take photos to ensure clarity later.

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

Before your trip, confirm if your rental includes roadside assistance. This can be crucial in case of breakdowns or emergencies during your rental period.
