Wizz Air WizzAir WhizzAir Whizair I think this is not an airline, but a scam! Internet

I hated everything about this airline. You have to pay extra for the standard luggage, extra to sit together and so on. But I will get straight to the point, that makes me mad. They literally robbed me of 90 Euro, calling in a "price of an offline checkin". Ninety blinking euro! Almost 120 dollars for what should be zero. Needless to say, I didn't receive an email or any other type of warning, that I should chech in online. And at the airport they told me that I ether pay or stay. And same for about 1/3 of all passengers. Its the first and surely the last time I use this airline! Crooks! Never, ever again! I haven't been so humiliated ever.
