Roughly this would cost £1-2m a year in fees (My personal guess not BA figures), and would not bring in any CASH to put into pensions etc.
It may not bring any cash to put into NAPS, but it would certainly improve BA's net asset value in relation to it's market capitalisation (which is increasing all the time in recent weeks, BTW). Something which BA itself draws attention to when trying to 'spin' to us all how bad things are.
