Some confusion here, I feel.
BA is a Public Limited Company. It is responsible to its shareholders. It is not a social service, an arm of Government or a regional development agency. It operates in one of the toughest market sectors in the world, where politically-led disaster is always just around the corner.
BA is pulling in its horns in Europe because a combination of low-cost competition and hidden subsidies to major rivals (compris?) means that there is little realistic chance of making any money there in the forseeable future.
Plenty of people can criticise BA for its performance, but it is just plain silly to criticise it for not trying to be all things to all men. If BA sees a market in which it can operate profitably, I am sure that it will be in there. There is absolutely no room for soggy sentimentality and nostalgia.
