We flew Premium Economy in April, and I found the food 'okay', also I am a very plain eater and extremely fussy.
We don't set high expectations, and have never flown with anyone else so cannot really be over critical.
I don't expect gourmet dining either but from what I can remember this year I had no real complaints, although I seem to remember a tub of ice cream that hadn't thawed out after 2 hours.
Our son never eats much on board so we take sandwiches & crisps for him.
