You mean the company that spun off its core businesses to form two very successful sub companies after hostile take over bids in the early 1990's? The two businesses being the pharmaceuticals and agrochemicals businesses Zeneca and Syngenta? Sadly the brand ICI died this year but the core businesses still exist within the two above companies. This is why the pilots were so opposed to Open Skies.
Hostile takeover bids for BA? In the current market? Sorry, very unlikely. Also the ability of the company, despite its seemingly sloth like management, to adapt it's core business is quite an asset. Whilst most airlines have been crawling out from under the bankruptcy rock, BA has been cleaning its debt and recovering a stable financial footing.
I doubt we will see
BA die like a dinosaur or a dodo
but I do see a bit of 'personnel restructuring' coming. The running of a small operation with a limited route structure ala 'Silverjet' is somewhat different to the LH operation run by BA.
