This was a change that was due to come, but has been shelved - indefinitely, it seems.

The changes that have come about are the new amenity kit (the pen is not the only novelty - I think ear plugs are also new), new bigger square pillows with a fabric cover (small change, but actually noticeably different and better), and a choice of papers (ie the Telegraph in addition to the Mail).

Which makes a J- product very appealing if you can get it at BA's Y+ prices. (But, as I have often said, I prefer Y+ at Y+ prices to J- at J- prices.)
