I'm planning to go from Chur to Florence on the same day.
The plan is -
1. Chur -> Tirano riding the Bernina Express. Arrive in Tirano at 12:49pm.
2. Assuming this is on time, there is a Trenord train at 1:08pm to milan which takes 2.5 hours - so arrive 3:40pm.
3. Then take the 4:10pm trenitalia train to Florence.
Whats the best way to approach the tickets for 2 and 3?
I'm planning to buy the regional ticket to Milan when i get to tirano, but for Milan to Florence I'm planning to get a discount ticket ahead of time (super economy or the frecciaday).
My question is if I miss the 1:08 connection, the next train is 2 hours later. So what are my options for the 4:10pm train. Can I get a new ticket issued given this is a discounted fare which mean I must take only that train at that time. Does it make a difference if I buy both trips in one transaction - so Tirano -> Florence? I noticed trenitalia sells this.
If the ticket can't be replaced for a later train, should I pay the premium and get the next level up economy ticket, so that if the train is late, I can change?
Thanks
