Ours and the three VS slots would indeed make a daily, very interesting. From our point of view 4 days a week, though a welcome breakthrough, is not very good news. The problem is what to do with the a/c on the other 3 days, another route would be fine but if it's not out of LHR it becomes a bit of a nightmare, I think the company would have preferred nothing or 6-7 days a week but feels it can't turn the 4 down as it's been asking for longhaul out of LHR for so long.
