Well they could do more. If a passenger wants to fly to a country that requires a visa the airline wants the details so they don't have to fly the same passenger back on the next flight. Wizz don't even ask any questions about reasons for travel on their booking engine via tick box answers but neither do any others I guess. The difference for Wizz it they have now finally admitted what we all knew and that they are breaching UK regulations because there is money to be made.
