I haven’t seen any signs of SQ attemtping to improve customer service on board and agree with others, it’s penny pinching at every turn. They rely very much on the hard product as a sales pitch and think people don’t notice the rest. As I’ve never been a fan of the current J seats and I don’t tend to watch IFE the soft product really does come under scrutiny.
In both F & J (can’t comment on Y) the soft product has been in decline for several years on an incremental basis so that you almost don’t notice but if you could take a snapshot and compare it over periods of a couple of years at a time over the last ten years you would get quite a shock.
I now fly SQ when they are the most convenient option and there isn’t another carrier I prefer more (QR, QF, EK, EY, TG and a few more) on the route at the time I need.
