Insider Tips to Get a Cheap Car Rental at Ontario, CA Airport
1. Book Early (Especially in Peak Season)
Car rentals can spike during holidays, summer, and weekends. Booking at least 2 weeks in advance can save you 20–30%.
2. Compare Rates Online
Use comparison tools like Kayak, Expedia, or directly check with Mr. Rent a Car (our local affiliate near ONT) for exclusive deals. Don’t just go with the big names — independent rental agencies often offer better prices and personalized service.
3. Look for Off-Airport Options
Most travelers search “Ontario airport car rental 24 hours” — but going off-site (just outside airport property) can avoid high taxes and fees.
💡 Mr. Rent a Car is working to collaborate with a trusted partner near Ontario Airport to offer competitive pricing just minutes from the terminal.
4. Use Discount Codes and Memberships
AAA, AARP, Costco, and even credit card companies like AMEX or Visa offer rental discounts.
5. Avoid Add-Ons You Don’t Need
Rental companies make money off extras like GPS, toll passes, or insurance. Use your phone for navigation and check if your credit card or personal insurance already covers rental cars.
