Unfortunately you have purchased an economy fare, per the fare rules:
Venice to Rome:
- No booking or ticket changes are allowed with this fare. This fare is not refundable.
Rome Termini to FCO airport this ticket is a regional train and is valid for 2 months from date of purchase on that route on any regional so you can change that to a different tme or date, you cannot cancel it however.
