Hello Everyone!
I am flying into Belfast next week.
We are flying from Detroit to Amsterdam to Belfast.
On the return we are flying from Dublin to Paris to Pittsburgh.
I was wondering where we will have to go through passport control and where we will go through customs? I have been trying to research this, but I find it difficult, so I'm hoping someone could just let me know. I know Ireland is not in the Shengen, but both the connecting airports are. I am checking my luggage through to Belfast and checking it back from Dublin to my final destination in the US. Will I have to check them in again at any point?
Thanks!
