Ticket prices vary based on flexibility. Super economy fares are the cheapest but cannot be refunded or changed and are usually the first to sell out. Economy fares can be changed once before departure but cannot be refunded. >Base fares are the most flexible and expensive, allowing unlimited changes and refunds with a fee before departure. To secure the lowest price on high-speed trains, it is recommended to book Italy train tickets in advance.
