10 tips to save on your car rental in and around St. Louis

1. Use filters to find the right car: Refine your search by vehicle type and specific features. Whether you need an SUV for extra space, a convertible for summer drives, or an economy car for budget-friendly travel, filters on Expedia can help you identify the perfect vehicle for your trip.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it's wise to reserve your car well ahead of your trip. By booking in advance, you're more likely to secure lower rates and enjoy better availability, especially during peak seasons.
3. Consider a smaller car for savings: Smaller cars are typically less expensive to rent and easier to maneuver 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 could also apply to renters over 70 years old. Always verify the age requirements before making a reservation.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, which means you must return the car with a full tank to avoid additional charges. This is generally the best option. Other policies may include full-to-empty or prepaid fueling options, which are acceptable as well; just ensure that you return the car empty in those cases.
6. Save on city and airport pickups: You may incur a surcharge when picking up your rental car at airports, but the added convenience might make it worthwhile.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provide peace of mind in case something unforeseen occurs during your trip. It's simple to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning long road trips, seek out rentals that offer unlimited mileage to prevent incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
