Suspect feedback may have been that very few GCHs choose to fly BA because of the open doors policy and taht therefore taking away the benefit would have little/ no impact on business levels for BA.
Big thumbs down on this
I didn't use the benefit much but it was really handy when I did. Used it in DAC - when they still flew there - SIN, BKK, in both cases when flying intra-Asia, LOS, when I actually used the lounge computers to book a BA flight.
Arghhhh!
