To whom it may concern;
I will have a flight from Zurich to Warsaw airport two days later. As I know that Switzerland is a part of Schengen area, however; I am not quite sure whether there is any passport control or not. I am so happy that if anyone knows this situation, please write the answer
There is an ID check (passport or official ID card, if you are an EU/EEA citizen) at check-in and at security in all airports in the 26 Schengen countries, so you can expect to show your passport at Zurich Airport.
Zurich > Warsaw is a within-Schengen flight so you will not go through border (passport) control on arrival. You will be channelled straight through to baggage reclaim.
