Though Italiarail will charge a booking fee, typically of around €3.

The Early Bird service

Italiarail has launched an 'early bird' pre-booking service for journeys by Frecce trains.
Tickets can be booked up to a year ahead of travel at a flat-rate price per route, before the tickets have been released for sale by Trenitalia.
If when they are placed on sale, the price is cheaper than what you have already paid to Italiarail, it will automatically refund the price difference.
Conversely, if the price is more expensive, you won't be charged the price difference.
You can also have the peace of mind of securing your seat(s) on the Frecce train(s) when you are first planning a trip.
If before the tickets are placed on sale, you decide to change your plans, you can request a refund; but once the tickets are released for sale, you will then be bound by the terms and conditions of the ticket(s) you have booked.
