10 tips to save on your Union City car hire

1. Use filters to find the right car: Refine your search by selecting vehicle types and specific features. Whether you're looking for an SUV to accommodate extra passengers, a convertible for summer drives, or an economy car for budget-friendly travel, utilize the filters on Expedia to discover the best option for your journey.
2. Book in advance to help lower costs: Rental rates vary based on demand, so it's wise to reserve your vehicle well ahead of your trip. By booking early, you're more likely to secure lower prices and enjoy a wider selection, especially during peak travel seasons.
3. Consider a smaller car for savings: Compact cars are typically less expensive to rent and easier to maneuver in crowded areas. Mid-size vehicles strike a good balance between affordability, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily fees, and certain types of vehicles—such as SUVs or luxury models—might not be available. Similarly, renters over 70 may face restrictions. Always verify the age requirements prior to booking.
5. Check fuel policies: Some rental companies require 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 most economical option. Others may offer full-to-empty or prepaid fuel options, which can also be convenient, but make sure to return the vehicle empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the 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: Rental car insurance can protect you from unexpected expenses and provides peace of mind during your travels. It's easy to add insurance when booking through Expedia.
9. Consider unlimited mileage: If you're planning extensive road trips, seek out rental options that offer unlimited mileage to avoid incurring extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a vehicle.
