How quickly have you received answer from AY for these claims? I sent my claim on 18JAN, received a short reply from the person "in charge of my case" on 03FEB saying that she will investigate the case and contact me again asap, still waiting. This claim was about A350 4h delay.
Their first reply came in about 4 weeks after I sent the claim and the 2nd reply in about a week after my reply.
