What with the continuing operational losses, the excessive focus by higher management on high-yield business traffic which has now dropped away, the gross deficit in the pension fund, and now personnel who not only show no inclination to accept the cost control measures but want to hit the revenues and inconvenience the customers at a peak period for revenue traffic, the net worth of BA as am ongoing business must now be substantially negative.
So the best thing is to cut the losses quickly and go into administration. A new carrier, with new capital, a freshly-purchased new or secondhand fleet, new personnel on new Terms & Conditions, could probably be back up to about 50% of current BA volumes in two or three years. They would never get it all back but they would get a proportion, the more worthwhile bits.
Sorry shareholders, sorry existing employees, sorry those with pensions paid from a pot no longer being funded by forward operations. That's how it is when a business gets into a hole and then some of the team refuse to help get it out again. Businesses don't have to last for ever.
