Just got off G-BNLN in MIA. Having feared the worst it wasn't as bad as expected. Generally mostly clean, everything worked as expected. It was a bit tatty, with some of the wall panels not quite aligned, but a generally good flight. It probably helped that it was our first ever flight upstairs

If I'd wanted to watch the in flight entertainment my verdict would have been rather different however - low res and barely visible with the window shade open.
