Atmosphere had every right to expect Silverjet to make a profit in March. The CEO had previously given guidance to the stock market to say that it would. The fact that it didn't merely underlines the point that they are now well and truly out of favour with the City - you only make statements like that if you're 110% sure that you can achieve it. They haven't and so this will be another hit to their credibility in investor circles.
The loadfactor figures are also not a direct indication of profitability. You can have 100% loadfactor and still lose money. Ask BCal - they did it for years on Gatwick/JFK.
