- Luggage
- Carried free. ATM's current metro rules refuse only items over 90 cm on any side at the gates and mention no charge; a 2007 company regulation still on ATM's site asks for a ticket for a case over 50 cm, and the current rules do not repeat it.

It is the same EUR 2.20 as any ride across Milan, with no airport supplement, and under-14s ride free. Against Malpensa's EUR 15 train and Bergamo's "from EUR 9" coach, this is the whole difference between the three airports.
The Duomo is not on the M4: change at San Babila to M1 for one stop, or at Sforza-Policlinico to M3 at Missori. For Milano Centrale, M3 from Missori is five more stops. The change is on the same ticket, within 90 minutes.
Tap the same card in and out. A card that is not tapped out is charged the fare to the farthest station plus an extra; a card can pay for one person at a time; and cards do not work on Trenord's S lines from Dateo or Forlanini.
ATM's printed sheet says every 1 to 3 minutes at weekday peaks; as of September it is every 4. Either way you will not wait long. After 20:00 it is every 6.
Last train from Linate 00:26; the NM4 bus takes over at 00:40 on the same ticket. First train 05:40, or 06:00 on a Sunday.
Anything over 90 cm on a side is refused at the gates. Ordinary suitcases are carried free under the current rules.
