Oil price will kill Cargo
The next Oil price bonanza will kill 50% of all Cargo Airlines worldwide.
Think about it : with oil price reaching triple digits soon, eventually 200 $ plus it just doesn't make sense anymore. People will have to wait for a shipped Ipod, eat locally farmed fish and simply stop buying roses from Kenya. It's madness anyway from an environmental perspective and anyway unsustainable. Oil peak will happen soon or even has happened already, there is simply no way oil is not going to be much more expensive than today. Forget about synthetic fuel made out of crops or about tar sand from Canada, too expensive for Jet fuel.
Passenger traffic will decline as well, but is probably a little less price elastic.
