ET > CE last week.
It was my first flight on BA since becoming Gold and towards the end of boarding, CSM came to congratulate/thank me and invited me up front.
Even though it was a loss of legroom [from EER to row 3], I appreciated the gesture.
Apparently, this was supposed to be mentioned during my check in [just about reaching Gold, not upgrade], but the lady in First area was a bit confused and flustered [admittedly it was 5am], so she didn't do it.
