Expedia is a big believer in making travel accessible for everyone, that’s why you can reserve your rental car without paying in advance. With our Book Now Pay Later option, you can just hand over a valid credit card to pay the cost in full at the pickup spot. How’s that for stress-free? The rental car company will also place a hold on your credit card for the security deposit. For some cheaper online deals, you may be required to pay at the time of booking. Be sure to take note of which payment options are available for the rental you’re interested in.
