Hello RolandP ,
Before putting my question here I looked into the same page you shared.
There, it is written: “You can purchase the Night GA Travelcard for CHF 99 per year up until one day before your 25th birthday. It is valid for one year. ”
What is still not clear to me is that there can be two moments: i) Purchase moment and ii) First day of validity (up to 3 weeks after purchase moment).
So, does the quote I shared apply just to i), or does it apply to both i) and ii) ?
Thank you!
