No capacity constraints whatsoever a couple days ago. Took a 15 hour flight in F (DXB-RU) and visited the bar a couple of times to stretch my legs.
On the first visit, all seats were taken so I stood while having a drink on the side counter.
On the second visit, the larger table was fully occupied and the smaller one had 2 pax. Turbulence started so I was directed to take the third seat for a few minutes, until we were cleared to move about the cabin.
I also noticed that people were loud and cheerful ... perhaps that is the downside of the daytime flight??
