really concerned with our itinerary. we booked international flight to rome connecting in mxp. after booking it online (cancellation/changes out of question), i realized we only have 45 minutes in between flights. first time flying to milan, i have no idea how big MXP is. read that i have to go from T1A - T1B where domestic flights are? Do we have to pick up our luggage and recheck it back for the domestic flight? if we miss our connection, what are my options? really not familiar with how this works, so i am really concern about this..Dont want to ruin everyone else's vacation !! Thanks in advance!
