Two recent flights with Emirates in J and both times my first-choice meal choice was unavailable. Now, I recognise the constraints involved and I understand that you can't always satisfy everybody's meal choices. But, on both occasions I was near the front of the business-class cabin and far from being the last passenger to make a meal choice.
I might suggest that this could be a case of 'financial tightening'. An almost inedible fish curry is certainly cheaper to produce than a 'Sous-vide flat iron beef steak'.
Cost cutting or what?
