I'm confused about what the actual 'start date' is.
Is it when the exchange order is presented and when the pass is received?
Is it the first time you make a reservation using the pass?
Or is it the first time you travel using the pass?
For example, if I exchange the pass and reserve a seat on the 12th for a train that leaves on the 13th, which of those dates is the start date?
Thank you!
