Amendments, Cancellations & Extensions

Sometimes plans change and you no longer need a car rental, or you need to make an amendment to your reservation. Here you can find out information about charges for canceling a reservation, how to go about extending a rental if you need a car for longer than expected, or how to amend a reservation. If you have made a “pay on arrival” reservation, the good news is that many of these changes come at no cost. 

I am currently in the rental with Sixt, can I extend the Rental Agreement by phone?

All rentals can be extended up to five additional days. If you need an extension over the length of five days, this will require a new reservation and rental agreement. Please contact us vial mail reservations-usa@sixt.com for your extension needs.
