The 90-minute ticket is Milan’s standard fare unit for ATM, the city’s transport operator. It covers one metro ride plus any number of bus or tram changes, all within 90 minutes of validation. What it does not cover is a second metro ride — even inside that same 90 minutes, once you’ve exited through a metro turnstile, you cannot tap back in on the same ticket.
That single rule causes more confusion, and more fines, than anything else in the fare system. It is worth understanding properly, because the logic behind it is different from how the ticket behaves on the surface network.
How the ticket actually works
ATM sells the 90-minute urban ticket under the name biglietto ordinario urbano. It is valid on the metro, buses and trams within Milan’s urban zone. A contactless bank card works directly at the gates — no need to buy a paper ticket in advance. The current fare is published on ATM’s own site, atm.it, and is worth checking there rather than trusting any article, including this one, since it has changed before and will again.
The 90 minutes start when you validate: tap in at a metro turnstile, or tap on a bus or tram reader. From that moment, the clock runs regardless of how many vehicles you use.
The rule that trips people up
On buses and trams, the ticket behaves the way most visitors expect. Get off one tram, board another, tap again — no penalty, no restriction, as long as you’re inside the 90-minute window. Surface transport has no single-use limit built into the fare.
The metro is different. Milan’s metro gates are a closed system: you tap in, you tap out. That exit tap is not a formality — it closes the journey. If you leave a station and try to re-enter the metro on the same ticket, even five minutes later and well inside the 90-minute window, the gate can reject it, or accept it in a way that inspectors treat as fare evasion.
This matters because the failure mode is easy to fall into by accident. A visitor surfaces at a station to check a map, walks back down, and taps in again assuming the ticket is still running. It often isn’t, in the sense that matters: one ticket buys one metro ride, not unlimited metro re-entries within the time limit.
What one ticket allows, at a glance
| Action | Allowed on the same 90-minute ticket? |
|---|---|
| Metro ride, then exit | Yes — this is the one metro journey the ticket buys |
| Metro exit, then re-enter metro later | No — a new validation is required, even within 90 minutes |
| Tram to tram, or tram to bus | Yes, any number of times, within the 90 minutes |
| Bus, then metro | Yes — the metro ride can come before or after surface legs |
| Metro, then bus or tram | Yes — this is the intended pattern: one underground leg plus surface connections |
The pattern the fare is built for is simple: one underground leg, combined with as many surface changes as you need to complete a journey. What it is not built for is treating the metro itself like a hop-on, hop-off network.
Why inspectors treat this seriously
ATM runs regular ticket checks on the metro, and inspectors carry portable validators that read a card’s tap history. A ticket that shows an exit tap followed by a later entry tap, with no fresh validation between them, reads as an attempt to travel on a single fare twice. The fine for this is set by ATM and published on its own site — it is not a matter of interpretation at the gate, and claiming not to have understood the rule does not usually change the outcome.
This is one reason the transport section of this site treats getting around Milan as a structural question, not a checklist of stops. Understanding how the gates actually work saves more time — and money — than knowing which line goes where.
Passes that remove the problem entirely
For a day of heavy metro use — several separate rides, spread through the day — a day pass removes the exit-gate issue altogether, since it isn’t tied to a single validation event. ATM sells day and multi-day passes alongside the 90-minute ticket, and the choice between them is really a question of how many separate metro entries a day will involve. Anyone building an itinerary that crosses the city more than twice should work out that number before buying tickets, not after.
The same logic applies to arrivals from outside the city. Someone connecting from Malpensa, Linate or Milan Bergamo airports onto the urban network needs to know which ticket type applies to which leg, since the airport express services and the urban ticket are usually separate products.
A note for residents and longer stays
Visitors buying single 90-minute tickets are not the only readers of this page. Anyone staying more than a few days, or living here, generally moves to a rechargeable card loaded with multiple journeys, or a weekly or monthly pass — where the metro re-entry restriction stops being relevant, because the pass covers unlimited validations rather than one journey per ticket. ATM’s site lists the current structure of these passes and how they’re loaded.
For a single day of sightseeing with two or three metro rides planned — say, the Duomo, the Castello Sforzesco and Brera — buying two or three 90-minute tickets, or one day pass, usually costs less confusion than trying to stretch a single ticket across the whole day.
Sources and how to check
The fare structure described here — one metro ride, unlimited surface transfers, a 90-minute window — is set by ATM, Milan’s transport operator, and published at atm.it. Current fares, day-pass prices and fine amounts are all listed there and should be checked directly, since they are revised periodically and any figure printed here would age quickly. Milan’s city council also publishes general transport information through its own site, comune.milano.it, for readers wanting a second source.
More on how this site sources and checks its transport and museum information is on the About page, and what the site collects from readers is covered in the privacy policy.
