Swiss Pass coupon

My wife and I are planning a trip to Switzerland for 5 days.

Use the Swiss Pass for 4 days.

But when I am going on a day trip, I saw a Swiss Pass coupon.

I heard that if you have this, 1 person is free.

Can I use this to freely ride trains, buses, ships, mountain trains, and cable cars?

And I’m going from Milan to Lucerne, can I take advantage of this? Please guide. Then I think I can plan a better Switzerland trip with my wife.

Thank you for your query.

If you mean the following pass, it is only valid for 1 person who owns a Half-Fare Card (all details and conditions can be found in the link): https://sbb-tickets.cc/en/campaign/4-tagespass/conditions.html

This pass is only valid within Switzerland and not for travel to or from abroad.

I wish you a pleasant stay within Switzerland.

Kind regards,
