Hi everyone,
I’m travelling with my elderly parents and noticed recently that trains from Zurich to Italy have changed route recently.
Some of the trains now say reservation not required. I’m worried that we won’t be able to get a seat if you can’t reserve a seat on these trains. Is there a way to guarantee a seat on these trains? Please see below a screenshot for your reference. Also, the direct trains which say reservation required on the app then say on the reservation website that prices are unavailable- are these booked out?

Thanks all!
