Maybe they all hedged fuel at a ridiculous price a few months ago making these aircraft unaffordable.
Now that the price has dropped to less then half they may be 'back in the game' so to speak, for a carrier that has yet to hedge fuel or is about to hedge at a very good price....
I'd like to see the total cost once check in, baggage, food, in flight entertainment, a comfy seat which can recline etc etc is added to the basic price. There's a lot of opportunity to get you on board with a cheapo ticket then screw you once your sitting there for 10hrs. Its not a short hop like in euro land.
