Due to covid, I had a 747 upper deck trip cancelled. 64K on the way back as well; never done it before so have missed out on an experience that it looks like is now gone forever. Gutted
At least I did travel on the upper deck previously on a VS 747 and, although it is not quite 1K on BA, I sat in 6K on a VS 747, so did manage to sit right in the nose of the 747.
