In a mistaken belief that BA's business was "premium passengers" and a failure to recognise that they were in the mass transportation business with a particular legacy monopoly over Heathrow, "go" was sold to easyJet as a non-core enterprise, allowing easyJet to grow substantially at low cost.
Nobody is out to get hard-working staff, but the airline's cost structure survives not as people are prepared to pay so much for BA, but that BA offers the vast majority of routings from London through a legacy structure.
The proof in the pudding is that it cannot afford either to base itself or provide any services from any other city in the UK other than London (except routings into London).
Economics always wins...eventually. Sad as it might be.
And no, I am not prepared to support it through my taxes.
