Planning on renting a car from Austin Bergstrom airport in October. I don't have a credit card so will have to use my UK Debit card. I have read that avis don't accept debit cards when the person is under 25. Is this correct

I have also read that UK and USA debit cards are different and that uk cards are more like credit cards so do you think they would accept it from a 24 year old.

Thanks
