What Fox Rent a Car offers at Ontario Airport
Fox Rent a Car operates a rental counter at Ontario International Airport (ONT) in San Bernardino County, California. You can pick up and return vehicles at the airport terminal, which means you don't have to arrange separate transportation to an off-site lot. Fox is a smaller national chain than Enterprise or Hertz, so availability and pricing can differ significantly from what you'll see at larger competitors.
The Ontario location handles standard rental transactions: you show your driver's license and payment method at the counter, review the vehicle condition, and drive off. Like all airport rentals, Fox charges a facility fee on top of the base daily rate — this fee is set by the airport authority, not by Fox, and applies to every rental company operating there.
Key Takeaways
- Fox Rent a Car's Ontario Airport counter is in the terminal, so you can walk directly from baggage claim to the rental desk without leaving the building.
- Airport facility fees are added to your daily rate and are the same whether you rent from Fox, Enterprise, or any other company at ONT.
- Fox often undercuts larger chains on base rates, but you should compare the total cost including fees and insurance across at least two companies before booking.
- You must present a valid driver's license and a credit card in your name at pickup; some locations accept debit cards with additional requirements.
- Cancellation policies vary by rate type, so read the terms when you book rather than assuming you can cancel free of charge.
How to reserve a vehicle through Fox
You can book online at foxrentacar.com, by phone at their reservations line, or at the counter when you arrive. Online booking usually locks in a rate and lets you see exactly what you're paying before you commit. Phone reservations work if you prefer to ask questions about vehicle options or insurance before booking.
When you book, you'll need to enter your pickup date, time, and location (Ontario Airport), your return date and time, and your driver's license number. Fox will show you available vehicle classes — economy, midsize, SUV, and so on — and the total price for each, including the airport facility fee. The price shown is what you pay, unless you add optional insurance or services at the counter.
Booking in advance is usually cheaper than renting at the counter, because Fox's online rates are often lower than walk-up rates. If your plans change, check your confirmation email for the cancellation policy tied to your specific rate — some rates are non-refundable, while others allow free cancellation up to 24 hours before pickup.
What documents and payment methods you need
At pickup, bring your valid driver's license (U.S., Canadian, or international license with an English translation). You must also present a credit card in your own name — Visa, Mastercard, American Express, or Discover. Fox will run an authorization hold on the card to cover the rental cost plus a damage deposit, typically $200 to $500 depending on the vehicle class.
Debit cards are sometimes accepted, but policies vary by location and rental company. If you plan to use a debit card, call Fox's Ontario counter ahead of time to confirm they'll accept it and what additional documentation they'll need — usually a recent utility bill and proof of funds. The hold on a debit card can take longer to release than a credit card hold, sometimes up to two weeks after you return the vehicle.
You do not need to show proof of insurance at pickup if you decline Fox's damage waiver and rely on your personal auto insurance or credit card coverage. However, you should verify with your insurance company or card issuer before you arrive that they cover rental cars — many policies exclude rentals, and some credit cards only cover rentals in the U.S., not internationally.
Comparing Fox's rates to other Ontario Airport rental companies
Fox's base daily rates are often 10 to 20 percent lower than Hertz, Enterprise, or Budget at the same location, but the total cost depends on what you add at the counter. The airport facility fee is identical across all companies — currently around $12 to $15 per day at ONT, though this amount can change. The real difference comes down to insurance, fuel options, and any loyalty discounts you might have with a competitor.
To compare fairly, get quotes from at least Fox and one larger chain (Enterprise and Hertz both have Ontario counters) for the same vehicle class, dates, and times. Write down the base rate, the facility fee, and the total. Then check whether your personal auto insurance or credit card covers rental damage — if it does, you can decline Fox's damage waiver and save $15 to $25 per day. If you need coverage, Fox's daily damage waiver is usually $12 to $18, depending on the vehicle.
Fuel options also affect the total cost. Fox offers a prepaid fuel option where you pay for a full tank upfront at a per-gallon rate that's usually higher than local gas prices. If you decline prepaid fuel, you pay for whatever fuel you use at the pump when you return the car. Most renters save money by declining prepaid fuel and filling the tank themselves at a gas station near the airport before returning the vehicle.
Insurance and damage coverage at Fox
Fox offers a daily damage waiver (sometimes called a Loss Damage Waiver or LDW) that covers collision and theft damage to the rental vehicle. This waiver does not cover traffic violations, towing, or damage from off-road driving. If you decline the waiver and damage occurs, you're responsible for the full repair cost, which can easily exceed $2,000 for a collision.
Before you buy Fox's waiver, check your personal auto insurance policy and your credit card's rental car coverage. Most personal auto policies extend to rental cars, and many premium credit cards (especially American Express and some Visa Infinite cards) cover rental damage at no additional cost. If your coverage applies, you can decline Fox's waiver and save the daily fee. If you're unsure, call your insurance company or card issuer before you arrive at the counter — a five-minute call can save you $50 to $100 on a week-long rental.
Fox does not include liability insurance in the base rental price. Liability covers damage you cause to other vehicles or property. Your personal auto insurance typically covers liability on rental cars, but check your policy or call your agent to confirm. If you don't have personal auto insurance, you must buy Fox's liability coverage at the counter.
Pickup and return procedures at Ontario Airport
Fox's counter is located in the terminal building near the baggage claim area. After you collect your luggage, follow signs for "Car Rentals" and you'll find the Fox desk. Have your confirmation number and driver's license ready. The agent will verify your reservation, run your credit card, and review the vehicle's condition with you before you take the keys.
Walk around the vehicle with the agent and point out any existing damage — dents, scratches, stains, or mechanical issues. The agent will note these on the rental agreement so you're not charged for pre-existing damage when you return. Take photos of the vehicle's exterior and interior with your phone if you want a personal record. This step takes five to ten minutes but protects you against false damage claims.
When you return the vehicle, drive to the rental lot (the agent will give you directions) and park in the Fox section. An agent will inspect the vehicle, check the fuel level, and compare the condition to the original notes. If there's no new damage and the fuel level matches what you returned it with, you're done — the agent will return your keys and you can head to the airport. The entire return process usually takes five to ten minutes.
Frequently Asked Questions
Can I rent from Fox at Ontario Airport if I'm under 25?
Yes, but Fox charges a young driver fee (typically $15 to $25 per day) for drivers under 25. Some vehicle classes may not be available to drivers under 21. When you book online or call, Fox will show you the young driver fee in the total price, so you'll know the full cost before you commit.
What happens if I return the car late?
Late returns are charged at the daily rate or a higher hourly rate, depending on how late you are. If you're running behind, call Fox's Ontario counter as soon as you know — they may be able to extend your reservation and avoid the late fee. Check your confirmation email for the exact late return policy tied to your rate.
Does Fox allow one-way rentals from Ontario Airport?
Yes, Fox offers one-way rentals where you pick up at Ontario and return at a different location. One-way rentals usually cost more than round-trip rentals because Fox has to move the vehicle back. Get a quote online to see the one-way price for your specific route before you book.
Can I add a second driver at pickup?
Yes, additional drivers can be added at the counter for a fee, typically $10 to $15 per day per driver. The additional driver must present a valid driver's license and be at least 18 years old (or 21 for some vehicle classes). You can also add a second driver when you book online on Fox's website.
What if I need to modify my reservation after I book?
Log into your reservation on foxrentacar.com or call Fox's reservations line with your confirmation number. You can usually change the pickup or return date, time, or vehicle class, though the new rate may be higher or lower than your original booking. Check the terms of your specific rate to see whether changes are allowed free of charge.
