Hello Goothottuemb18
Welcome to the SBB Community.
We are a customer support forum run by volunteers; we are not the SBB customer service.
The luggage through-check to a destination in Switzerland is no longer offered to people with point of departure abroad, for security and customs reasons. It must have been a while since you have used this service, it discontinued more than 5 years ago.
Nowadays, you must take your luggage from the baggage claim area to the SBB travel center yourself, where you can recheck your bags for rail spedition, or you can book a porter service from CGS porter services to help you taking the luggage to the SBB travel center.
Kind regards,
Roland
