10 tips to save on your car rental in Illinois

1. Use filters to find the right car: Refine your search by selecting vehicle types and features. Whether you need an SUV for extra space, a convertible for summer fun, or an economy car for budget-friendly travel, utilize the filters on Expedia to find the ideal match for your journey.
2. Book in advance to help lower costs: Rental rates can vary based on demand, making it wise to secure your car well ahead of your trip. By booking early, you’re more likely to lock in lower prices and enjoy better availability, especially during peak seasons.
3. Consider a smaller car for savings: Compact cars are typically more affordable to rent and easier to park in crowded areas. Mid-size rentals strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle types—such as SUVs or premium models—might not be available. This can also apply to renters over 70. Always verify age requirements before making a reservation.
5. Check fuel policies: Some rentals operate on a full-to-full fuel policy, meaning you must return the car with a full tank to avoid extra fees. This is usually the most advantageous option. Others may offer full-to-empty or prepaid fueling alternatives, which are also acceptable. Just ensure you return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may be worth the cost.
7. Know your payment options: Most car rental companies exclusively accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind if something unforeseen occurs during your trip. It’s easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you plan to take long road trips, look for rentals that offer unlimited mileage to prevent additional charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
