If your train is delayed and you miss a connection in Italy, your rights depend largely on whether you booked your journey on a single ticket or separate ones. For those with a single "Integrated" ticket from Trenitalia or Italo, you are entitled to be re-routed on the next available train at no extra cost. You should head to the high-fidelity "Biglietteria" or customer assistance desk (like Punto Assistenza) to have your ticket validated for the new service. Under EU Regulation 2021/782, if the delay results in a final destination arrival more than 60 minutes late, you may be eligible for a "High-Fidelity" compensation (Indennità) ranging from 25% to 50% of the ticket price. If the missed connection is the last train of the night, the carrier is legally required to provide high-value hotel accommodation and transport. However, if you booked separate tickets (e.g., a regional train followed by a high-speed Frecciarossa), the second carrier is not technically obligated to honor your ticket, making a single booking a high-value necessity for long-haul Italian travel.
