Amendments, Cancellations & Extensions - Sixt rent a car FAQs
1. I have rented a car with Sixt, can I extend the Rental Agreement by phone?
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.

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.

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

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.
