Hi everyone,
I’m flying from Miami to Oslo soon and I had a question:

Do you pass customs in every connecting airport when traveling into the EU?

I have a connecting flight in Lisbon(too low a price to ignore tap Portugal) and then to Oslo from Miami, and I have some cans of Snüs left over which I know is prohibited everywhere outside the Nordic countries... so will I have an issue In Portugal?

I know you pass border control in the first Schengen country you land in because every time I’ve flown to Stockholm I get stamped in Finland or Spain, but I can’t recall what happens in customs will I have to pass through in Lisbon and Oslo as well or only Oslo?

Thanks everyone.
