EDIT: also check with your airline specifically. Many that I have looked at have no issue with plastic bags. There are few "general" rules when talking about bikes on an airline.
American airlines statements says Bike in boxes with specific dimensions. My trip ends in Milan, I will check online to see if they sell boxes
Thanks for the tip
