Is Y class anything to write home about on any (global) airline though? Not sure if that is the yardstick with which to measure, considering the provision of things which I think most Y flyers value which is decent IFE, edible meals and crew who aren't surly.
J though I agree hard product is below the global expectation on average. Full flat product across the fleet would go a long way to solving it.
F is pretty good imho but due for a refresh.
