I bought a flight from Milan to Anchorage that includes a transfer in Frankfurt (1 h. 40 m. stopover)
I don't have to collect my luggage, but I heard from other travellers I won't get in Milan my boarding pass for the second leg of my flight (Frankfurt-Anchorage).
Could someone let me know what I have to go or to do in Frankfurt airport?
Have I to exit from the security aerea?
Is the time connection enough?

Thank you for your help!
