Cheap AVIS Car Hire Deals at Singapore Changi Airport, SIN

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.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

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

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

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.

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.

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