Don’t Rent at the Airport – Sure, renting at the airport is convenient. However, it’s almost always more expensive. If you compare renting the same car from the same company, with the only difference being picking up at an airport versus picking up at a different location, don’t be surprised if you find out that it will cost you over $100 more for a five day trip to book your rental at the airport.

Rent Just for the Day – If you only need a rent car for a few days of your trip, only rent the car for the days you need. By not keeping the car overnight, you can save additional money.

Take Advantage of Airline Discounts – In many cases, you can find a special car rental deal that is offered by the airline you are flying on to San Antonio. It doesn’t take long to find out if this kind of special is available, but it can save you a lot of money.

Avoid Insurance Unless You Truly Need It – Because it puts money in your pocket, a rental car company is going to try to convince you that you need to purchase their insurance. However, before agreeing to this charge, you need to verify on your own if you will be covered. In many cases, your auto insurance, home insurance or even credit card will provide you with all the coverage you need.

Check for Damage – Before you take your rental car, double check to make sure it has no damage. Otherwise, you may be the one who ends up paying for it!
