I was in the flounge asking the staff if it was possible to move me and a work colleague so that we were sat together. I was told politely no as there was only 1 seat left on the plane.
When I boarded, I asked the crew, yes I was chancing it a little but thought it couldn't hurt. When they pulled out the ipad it showed around 20 empty seats around the plane and they were happy to move us so we could sit together so it does seem that the lounge information doesn't always match the reality. Maybe theoretical seating (but I think not as the guy we were next to had no status according to the ipad) or maybe a block for aircraft trim, whatever, it didn't seem to bother the crew to move us so it's worth bearing that in mind.
I defo didn't want to be one of those people asking other pax to move or be moved! I couldn't live with the stares.
