Amendments, Cancellations & Extensions - Sixt rent a car FAQs

1. I have rented a car with Sixt, can I extend the Rental Agreement by phone?

Only one extension can be done over the phone per rental, and it has to be the first extension. Extensions can be done up to 5 days by phone. A new approval for the security hold may take place. Any extensions beyond the extended 5 days must be made/agreed directly with the renting branch.

2. What is the charge to cancel a reservation?

If you have booked a prepaid reservation you will be charged a cancellation fee. The cancellation fee will be up to 3 days of the rental rate including additional extras.  If the rental is less than 3 days, the cancellation fee will be the full rental amount.  

 

Pay-on-arrival (flexible) cancellations may be done without cost.

3. How much notice must I give to cancel a reservation?

Cancellations can be made at any point prior to the start of the rental. 

 

Please note if a “pre-paid” reservation is not cancelled prior to the start of the rental, and the vehicle was not collected (no-show), the rental amount will still be charged to the customer in full. 

4. How do I amend or cancel a reservation?

Amendments or cancellations can be made via our amendment page or by e-mailing our Reservations Team; reservations-usa@sixt.com. 

5. What is the charge to amend a reservation?

Amendments can be made to “pre-paid” reservations up to 48 hours prior to the start of the rental (subject to availability) at a fee of 28.00 USD (exclusive of sales tax). However, if the rental cost increases as result of the amendment then we do not charge the amendment fee. Amendments to pay-on-arrival bookings can be made at any time free of charge.

 

Please note all amendments are subject to availability and current pricing.
