£425m profit may seem a lot but as a profit margin it's still pretty thin and well below profits before the downturn. And if you look at cash (often viewed as a true measure of performance), that actually went down. Also, the long suffering shareholders are still not getting a dividend and have seen the share price nearly halved over the past year.
If you look at the vast number of airlines posting losses and the fact that almost every other legacy carrier in Europe is going through a major restructuring it's an absolute unequivocal vindication of the need for BA to go through permanent structural change.
