That would depend upon what type of fare you have purchased. If you have purchased a super economy or economy fare then there are no changes or refunds allowed by Trenitalia. If you have purchased a normal fare then you may change only the date & time never the route or number of passengers.
We can assist with the change there is a $20.00 change fee plus any fare increase but we would need to know your order number
