I am going to Belfast, Northern Ireland in May for the sixth time and I've always flown directly into Belfast International before, but it seems as if they are no longer doing flights via Newark (ERW) and BFS. :(
So, my new flight plan is Columbus to Belfast via Philly and Glasgow, Scotland on American. My question is when will I go through passport control/ customs? I have a ticket on American Airlines to Glasgow and then on FlyBe to Belfast. It's a single itinerary, so I believe I should have a through ticket even though I'm switching airlines.
Any idea on what things will look like in Glasgow (GLA)?
