I got to the check in counter and I was told that each person in my party had to pay 35 Eur to do check-in at the airport. I was informed that it was my responsibility to have done my check-in online or via the Wizz Air app. However, I went back to check every single email that Wizz Air sent to me. Not a single one of them mentioned it.
