I can add another data point to the pink steak. The best I’ve had in the air and a good steak in its own right. I did ask for it to be rare but I don’t think they did anything too special to make it so. Would definitely order again.

Headphones much better than old ones but not a patch on Bose active noise cancelling (unsurprisingly).

Cutlery, stemware etc probably the most notable improvement, much as others have said. Really does make a difference to the feel of the experience.

Pyjamas look nice but come up enormous and sat very low on the neck / shoulders. A little bit revealing! Would definitely suggest getting a size down to normal. Slippers the opposite, they come up small...

Service as good as it should be, though familiarity with some aspects of the new products / menu were not there yet. As CIHY says this is probably down to the lack of specific training.

Overall a really enjoyable experience and good to see BA putting some effort into their premium product.
