It wasn't just selling it - couldn't even eat your own!
I was really not expecting to be able to get a change, sng my arm. As for tomorrow, was also told that both F and CW are sold out on BA117 with 1 oversold in WTP and 6 in WT.
Although have checked in, have not printed boarding card in case any better seats open up. Currently in 63K. Did have a heart in mouth moment earlier when it gave me three options for cabins 'front' 'main and 'upper' deck. Clicked on front but only showed me the lower deck with seats before the galley/loos.
