Got an email saying I missed the check in deadline 24 hours before my fight with Wizz air. It said I have to do an airport check in and get charged additionally. That's not correct since Wizzair check in runs till 3 hours before the flight. I found my booking number and did the check in myself throught the Wizzair app. Not sure whether the scummers called Kiwi get any commision by sending people do airport check in. Avoid them!
