Yes, you are permitted to take suitcases on the Rome Metro (Metropolitana), but there are specific "cultural" and "practical" rules to follow. In 2026, ATAC (Rome's transit agency) allows one large suitcase per person for free, but technically, additional or extremely large bags may require the purchase of a standard BIT ticket (€1.50) for the luggage itself. In practice, this is rarely enforced unless the bag is obstructing a significant number of passengers. The real challenge is the infrastructure: many Rome Metro stations—especially on Line A and Line B—lack working elevators or escalators, meaning you may have to carry your suitcase up several flights of stone stairs. During "Rush Hour" (8:00–9:30 AM and 5:30–7:30 PM), the trains are notoriously crowded, making it physically difficult to board with a large suitcase. To avoid the "wrath" of local commuters and the risk of being a target for pickpockets, travelers are advised to use the Leonardo Express train to Termini Station first and then use a taxi or a shorter metro hop during "Off-Peak" hours (10 AM to 4 PM).
