As a means of streamlining EC 261/2004 claims for compensation, it is important to keep them precise, short and to the point. There is no need of describing your losses and inconveniences. The entitlement is binary: you either qualify or you do not.

Thus, a complaint which describes consequential losses such as salary and other inconveniences and inidignities not only does not help you, but slows down and confuses the issues.

Here, a complaint specifically making a claim under EC 261/2004 for delay/cancellation compensation of EUR 600 for a delay of approx. 24 hours on a Band 3 flight and providing the date, flight number and your PNR & ticket #, will likely be processed in days.

You were also entitled to a duty of care and it sounds as though this was met.
