I did think the G-GATx had a middle table across 1B. Was it possible it was broken or just not pulled up? There would be a table across other CE seats. So it isn't the norm, but it is for any neos you may fly on (they are all at LHR).
The curtain should be there, but again it is absent on some of the newer A320neos at LHR. For that one again I can only assume it was broken and in need of repair.
Also, mainline cc are allowed to work Euroflyer? I am quite surprised about that.
