Can someone explain how this works for a journey from Lviv via Warsaw to New York?
If I have a flight originating outside the Schengen area, with a separately-ticketed connection in a Schengen country to take a flight to the US, do you need to go through a passport control in Warsaw if you have no baggage? For the sake of scenario let's take WizzAir Lviv to Warsaw and LOT from Warsaw to New York.
Does each airport in the EU allow you to stay in a non-Schengen area and web check in to proceed further (if no baggage)?
For some reason I thought that not all airports would have [airside] transit and, in some cases, one would have to go through passport control first and then go back through security?
P.S. Sorry, I edited my question with more accurate examples.
