My son will be flying from Florence to Newark via Zurich. Can he purchase wine in Florence airport and bring it home? I am assuming he can purchase the wine in a duty free shop after going thru security. He would then carry his purchase on the plane. Would he have to go thru security again in Zurich or would he just proceed to his next gate with the wine? Also, he would be bringing a small backpack as a carryon. Would his purchase have to fit inside that or can he have a separate bag of wine?
The purchase would only be a bottle or two of wine. He is US citizen and over 21 years old if that helps.
