Complaints provide the CAA (Civil Aviation Authority) with a great opportunity to listen, learn and improve from what our customers tell us. Therefore, we are dedicating time and resources to understand where and how we can improve.

Every three months, you can view key performance information on this page, which shows how we are performing and what has been learnt from complaints.

Each year we will publish an Annual Complaints Report providing a more detailed look at our performance on complaint handling.
