Milan to Florence

Not sure what you mean by not helpful. You need to get to the train station from the airport - two trains an hour and then take the train to Florence. Trenitilia will give you the schedule. trenitilia will not show the train from the airport. When are you going? Schedules are only posted about 90 Amy's out.

Trenitalia clearly shows all of the train runs from the Malpensa airport to Florence. You need to input Malpensa Aeroporto and Firenze S.M. Novella. I can easily see all of the runs. You can buy the tickets at the airport train station or you can buy them in advance at the Milan train station as you come through to go to Varenna. It doesn't look like you can buy this run online. I can't see the red purchase options at this time. At the Malpensa airport train station, you will need to take the Regionale train to Milano Centrale. Make sure that you don't take the one to Milano Cordona. At Milano Centrale, you change to a high-speed to Florence. The trip will take just under 3hrs.

Not sure why you have to go from Menaggio back to the airport and then on to Florence. Drop off or pick someone up? As we already know, there are 2 trains per hour Malpensa to Milano Centrale. You will need a separate ticket for the Malpensa Express train, and a ticket for the Milano Centrale to Firenza S. M. Novella. Here is the Trenord Malpensa Express schedule site.

Okay, I got it. Will go from Como Nord Lago to Milan Centrale Station, then catch the train to S.M. Novella station in Florence. Thank you, you've all been a great help, especially not backtracking to the airport.
