Is it possible to change a Trenitalia unused regional ticket after the time of departure of the train?
When you buy a Trenitalia online regional ticket, I have notice that you are allowed to ask for a change of the train. However, the conditions under which you can ask for such a change are not clear to me.
Let's suppose you have some problem, for instance a delay on the flight, so you can't board the train at the departure time stated on the ticket. Is it still possible to ask for a change of the train online?
What about an unused regional ticket that has already been changed: is it possible to ask for another change?
More generally, under which conditions you are allowed to ask for a change on your unused online regional tickets?
