Hello Voussuemiewh19
The door-to-door offer can only be booked if the luggage is collected from a Swiss address and sent to an address in Switzerland. If you hand in your luggage at the SBB ticket counter on the day of arrival, it can also be sent to an address in Switzerland. This takes approx. 3 days.
With the Swiss Travel Pass Flex you are also entitled to book luggage delivery.
I wish you a pleasant stay within Switzerland.
Kind regards,
FatimaH
