Wizz Air has been criticised for attracting a high number of complaints and not paying customers refunds by the UK Civil Aviation Authority (CAA).
The aviation body said that the Hungarian airline was "ranked as clearly the worst airline for complaints escalated to either Alternative Dispute Resolution (ADR) schemes or the regulator’s in-house complaints team in the third quarter of 2022".
ADR is when a complaint is settled out of court with the assistance of an impartial body, with Wizz Air attracting 811 complaints per million passengers from July to September.
