Can I change my car rental reservation for free?

Modification as such is free of charge. However, the change itself may incur additional costs due to daily price fluctuations.

We do not charge any fees for the modification but we can only change a booking with the supplier at the currently applicable rate. All offers and prices are constantly subject to change and daily rates tend to be higher as the start of the rental period approaches. As a result, the rental price may increase due to the desired change. However, it may also happen that the rental price drops for a desired change resulting in a partial refund.
