I hear all the time about people getting a free car rental upgrade. I'm looking at renting quite a few cars in the next few months and would like to lower my costs anyway I can. Is there anyway that I can get a guaranteed upgrade when I book a smaller car?
My Response:
Great question! Basically, you can get an upgrade one of three ways...
use an applicable coupon (Entertainment Coupon for example)
reserve a size car that will not be available at pick up
or just ask!!
Keep in mind that all three of these possibilities will never guarantee you a larger car at no extra cost. Even free car rental upgrade coupons state that the upgraded car is subject to availability at the rental counter.
I would say that the easiest way to get a larger car for free, is to reserve an economy or compact car. The car rental companies generally overbook these size classes consistently and will upgrade customers to a larger car.
But, also keep in mind that the rental company may ask you at the rental counter if you'd like to upgrade for x amount of dollars per day. Just say no, that you're fine with the compact. That way, if they actually don't have any compact cars, they'll have to give you a upgrade for free!! (This assumes that you would be ok with the compact car if it is available!)
Hope this helps!
