IF BA were smart they would flog off BACX and let it be a franchise operation with it's own competant management (it works elsewhere and worked before). There is a chance that the company may indeed do that - European mainlines tend to follow what US mainlines do with their regionals and across the pond they are flogging as fast as they can (although this has been slowed by the lack of popularity of airline IPOs on Wall St in the last two years).
Of course, it's BA we're talking about here, so the chances are rather than do the smart thing and flog it they'll probably just let it wither on the vine and then close it (already starting to happen if you think about it to the great joy of Richard and Brian).
