I haven't flown SN in a while but recently took them on a JFK-BRU flight (A330). Surprised to see how much 'cheaper' they are compared to the rest of the LHG airlines. The two biggest things for me were: 1) no pillow, only a paper thin blanket; 2) a very small water bottle provided after the meal vs the full size you get on LH/LX.
For a short flight like JFK-BRU I don't really mind it. Of course last time I took the SN A330 I was in business on my way to central Africa which was a far better experience.
