I'm going to be flying into Milano Malpensa airport, on a weekday afternoon. I'm told I would need to take the XP1 or XP2 train lines into the city.
About the train ticket...
Do I have to order it in advance?
If I do:
- Will the ticket remain valid if I take an earlier/later train on the same day?
If I don't have to:
- Is it easy to buy a ticket? e.g. vending machine with English UI?
- Is it cheaper or otherwise better to order the ticket in advance?
Also, same question about the other direction, which I will need to make about a week later and at 04:00 in the morning or so.
