I beg to differ.
If the "Y curry", as you call it, is on the J menu how does that make it Y? On a flight in September one of the meals on the F menu was chicken green curry and superb it was. I could not give a stuff whether Y got the same dish, does that make a difference to you? Why?

On a flight in October the prawn dish was not to my liking so I sent it back and because I did not care for any of the F alternatives I was given the J menu which did have items not on the F menu.

I recall we have crossed swords before on this subject:

"Oh, the Y classics."

My reply to that was:

Sneered the nouveau riche.

Thai Air have won awards for the quality of their economy class food so why not give it a try? It may be the same as in Y but does that make it inferior? It will also come in a porcelain dish in C or on a nice plate in F. You might find it tastier than the F class fillet steak where the apparently succulent red centre is actually dye.

Ask any visitor to Thailand who actually gets out of their fancy hotel and eats where the Thais eat, "Where did you eat the best Thai food? The answer will not be a five star hotel but more likely a roadside stall.

The quality of Thai food unlike western food bears no correlation to the quality of the surroundings and almost no correlation to price. In fact the reverse might be true, the chicken you eat at a tiny family restaurant could well have been running around the family yard the day before whereas your 5 star chicken will be sourced from a battery farm where it has been injected with growth hormones while alive, water when dead and then probably frozen.

Part of your subsequent reply was:

"I stopped years ago flying TG internationally, but I remember the Thai food was always too blund [sic] for me."

So how would you know anyway?
