Michigan to Barcelona: Delta/Paris stop?

Immigration: "Is this person allowed into the country"

Customs: "Are these goods allowed into the country"

 

Schengen applies to people (Immigration); so you will clear Immigration on your arrivial into the Shengen zone. Between Schengen countries you transit in much the same way you'd go between Oregon and Idaho.

 

Customs applies at most countries but is a tiny formality; and involves (generally) just handing someone a filled out card.

 

So; if you fly JFK-AMS-BCN (New York-Amsterdam-Barcelona); you clear immigration in AMS, and customs in BCN. You do not need to pick up and re-check your luggage.

 

THAT is a huge relief! Thanks. :D

Thanks to all of you for explaining this so well. It really seems complicated for someone flying to Europe for the first time. I've taken notes!
