I want to start off by saying I am not usually the person who leaves review but I feel obliged to do so with Wizz Airline. I would highly discourage people using Wizz Airline. We had a terrible experience at Istanbul. We was required to pay for extra baggage even though we had already paid for this online. The staff at the airport did not listen to us at all. When we paid for extra baggage we returned back and the staff at the airport took a picture of my husband’s passport and shared it on WhatsApp. We’ve never known this to happen so we inquired why they shared our sensitive data online. He did not answer us so we asked for his ID badge to make a compliant. He staff threatened to contact the police. He did not let us leave until the police arrived. When they arrived they circled us and did not listen to us at all. They threatened that if we had complained they would make us miss the plane. The reason why I am writing the review is because I saw they were doing this to vulnerable elderly people who did not understand what was happening. Please avoid using this airline.
