004wercras,
Not in a position to offer specifics, but take on board this.
Qantas hedged a good part of their fuel requirements for 2011-12 at worst case scenario of US$ 123.59 after increasing the fuel surcharge. The exchange rate then was $1.02 and the Jet fuel price was over USD$120.
I don't know what hedging has been done for 2012-13 but since then, the AUD has dropped to say, 0.92 to the USD representing about a 10% increase in the cost of fuel.
Jet fuel is over USD$120 again and if hedging (currency included) hasn't been done right, Qantas will have to again increase the fuel surcharge or the bottom line will take another hit. Doing that will be hitting the very people that provide the revenue.
Stand by for THAT announcement and then you'll know.
