Hi @AnneN
Thank you for your request.
Yes, you can cancel your ticket order online. If you purchased the ticket with a login, you can access the ticket in your profile on SBB.ch under ‘Orders’ and click on ‘Refund’ before the start of validity.
Please note that some tickets, such as supersaver tickets and Saver Day Passes, generally cannot be refunded. If you need further assistance, you may use the refund claim form for other refund requests.
You can find more information at sbb.ch.
I wish you a pleasent day.
Kind regards
KadijaR
