re: huge profit
A major reason why
VB has made a huge profit, is that they hedged the jet fuel at (using a nonspecific figure) $60 a barrel thou budgeted $80 so every barrel used they profited $20 dollars.
So the profit as such is more a saving than anything else. Hedging only started recently that why there is an increase of $$$$. Funnily enough the share price sky rocketed above the initial float price.
