Unfortunately, Thrifty at the San Antonio airport fits all of the negative stereotypes for car rental places. I scheduled a four door rental car on their website, under the "Thrifty chooses" the class of the car. With only one adult and three minors, and one suitcase, I knew any four-door car would be fine. Upon arriving at the rental counter, they said the only four-door car available would cost us $16 more per day, nearly doubling the cost of the car. Despite the fact that I reserved a four-door car of any class, they had hardly any cars available, and they refused to honor the reservation. Due to the long line and pushy sales person, I took the car and figured I would deal with it later. Calling the main thrifty customer service line during our trip proved fruitless, and we were told to talk to the manager upon drop off. This manager said because we had the car the entire time, they wouldn't refund the additional charges. Absolutely ridiculous - lack of customer service, and always trying to nickel and dime. Choose elsewhere - perhaps it is just the San Antonio airport location, but we are sorely disappointed in Thrifty. read more
