The only place I have seen mention of a senior discount is with the Swiss pass. Are there any senior discounts on other rail passes or on individual tickets? also the city buses, ships and mountain lifts?
Hello Arthur, welcome to MySwissAlps,
The Swiss Pass was discontinued in 2014. There is the Swiss Travel Pass now. All information is here: myswissalps.com/ swisstravelpass. There are hardly any senior discounts in Switzerland. That applies to the Swiss Travel Pass too. This page might be useful too: myswissalps.com/train/ ticketspasses/ practical/ discounts.
