After complete radio silence from Aer Lingus on this, I filed a complaint through the IAA website and I’m delighted to say that I received compensation of €400 and my expenses covered.
The complaint was dealt with promptly (within four weeks) by the IAA.
I would urge anybody in a similar situation to not bother wasting their time chasing Aer Lingus and go straight to the IAA website and submit a detailed complaint.
EI are a complete disaster at the moment with cancellations etc.
I had the great misfortune of travelling to Chicago on one of the ex Qatar A330’s. My goodness they are a complete and utter disgrace. I feel sorry for the cabin crew operating on those .... heaps as all they are dealing with are complaints…… broken IFE’s, seats not working, no WiFi. I got lucky on the flight home thankfully.
I’ve started using United for my travel to the US and have found them to date to be quite good.
