Only time I've every been asked to move, was to a better seat. Travelling LHR to LAX, I was sat in the second row of WTP as I'd failed to bag my preferred front row aisle (bassinet) seat. I'm just settling in and a pair of middle age ladies arrive, politely explain they are travelling sisters and would I mind moving forward one row (to where i'd hope to be sitting). Spent the flight sat next to a very attractive professional singer who entertained me with stories of meeting various celebs etc... A very enjoyable journey.
