Comforting experience for an older group. We were assisted with setting the GPS during pick up of the car we requested. Return was easy also.

This is only my second time using Alamo. Normally I am an Enterprise renter but I think I will be making a permanent switch. The first time I dealt with Alamo was on a Holiday weekend. I was driving back to Southern California from Seattle, Washington and my suburban broke down with about 400 miles to go. I could not find a rental car anywhere that would seat my entire team of 8. After seeing the desperation in my eyes, the Lady at the Alamo counter in Monterey Airport pulled me aside and said I'll find something for you and she did! This was my second time dealing with Alamo and I Didn't trust my truck to make the long trip from Southern Ca to Sacrament to Monterey and back home. I decided to rent a SUV. I used the carrental.com site and got a good deal with Alamo. The check in was quick and easy. About an hour away from Sacramento, I had a blow out. There was a free Freeway patrol service that changed the tire. Alamo was great and changed out the vehicle for the same one so I would still have a spare to drive home with. I appreciated their quick service and consideration for my safety. They are making a believer out of me.

The pickup was easy even though we had to leave the terminal shuttle buses seemed to be running slow both on pickup and bring back so allow extra time for this.

I dropped off my vehicle completely full. However, when I looked at my receipt I had a $60 gas charge, which is crazy because I only drove 90 miles and used 3.4 gallons. The charge was for 6 gallons which if they looked at the miles driven would have been impossible they were just trying to scam us. DIsgusting!

Good car, easy pick up. My only complaint is that the agent acted as if I didn’t have an option to NOT get extra insurance coverage and then she was less friendly once I denied it.

I wanted to give my experience the highest rating. The vehicle served me well. At one time I travelled with a weekly trip to some where on business, and I was a Hertz Gold member. I like Hertz. However, I opted for the insurance coverage from the Car Rents website, but it appears Hertz snuck their insurance onto my bill, too. I would like to have this clarified, and if there was extra insurance paid, that portion returned to me as I did not require insurance from both companies. I even returned it one day earlier. Meanwhile, I am waiting for my rental receipt via email, confirming all charges.

Everything went good. Clean car, ran well, Jeep needs to put bigger mirrors on their SUV's. Little mirrors in LA traffic suck.

How do I locate the cheapest rental car company at Ontario Airport?

You are in the perfect place if you want to receive the best price on your Ontario car rental. If you want to enhance your savings, try to:

  • Book as far in advance as possible. You will usually get the vehicle of your choice and save more
  • Compare and contrast all the deals available
  • Check the fuel and mileage policies. You don't want to be surprised with added costs

How old do I have to be to book a car in Ontario?

The youngest age to rent a vehicle in Ontario is 21. Be aware there is ordinarily an added charge for anyone under 25. Also note, the age restriction may be different for premium, large capacity, SUVs, or other higher category vehicles. Make sure you check the rental car company's policy before you book.

You'll find 12 rental car companies at the Ontario Airport. Rent from companies like Fox, Dollar, Thrifty, and Airport, plus several more. With over a dozen great choices, you are certain to get the price and the vehicle that you want.

Does the United States require car insurance?

In Ontario you do need to have insurance before you rent a car. You can buy additional insurance through your supplier for your trip, if you are concerned your insurance won't cover you while traveling through the United States. While many card issuers, like American Express or MasterCard, give some coverage, there are usually limitations. For example, they may not cover your rental car if you book a larger or luxury vehicle. Check your credit card issuer's policy before you book. Otherwise, as a U.S. citizen, you can also book Collision Damage Coverage through CarRentals.com at checkout.

What items will I need when picking up my car rental?

You will need to present your driver's permit and a credit card in your name.

Do I need to return my rental car with a full tank?

At CarRentals.com, we recommend a "full-to-full" policy. You pick up your rental with full tank of gas, and you should bring it back it filled up. If you want to keep your expenses lower, you should fill up your tank before you return the car. Stations close to airports or car rental places tend to have higher prices.

Should I get unlimited miles when I rent a car in Ontario?

Ontario has enough to keep you entertained, however you may want to head to other attractions to find out what else the area has to offer. You can explore the rest of the region without worrying about mileage limits when you travel to see what else California has to offer.

Can I get a one-way rental for my Ontario trip?

The majority of car rental suppliers offer one-way rentals in most cases. You may find it easier to drop off your rental car at a different location. Keep in mind there may be an added fee when you pick one-way.

What type of rental car would you recommend I hire at Ontario Airport?

That all depends on your needs and what you have in mind after you land in Ontario. Compact or economy vehicles are easier to park and great for short drives. If you are traveling with a bigger group, then a sedan or SUV will have enough room for all of you and provide a more comfortable ride on longer trips. Those looking for a touch of luxury on their Ontario getaway can choose the premium category to get a car like a Mercedes C-Class or Cadillac XTS or similar.
