My prediction. Oil will drop to less than $50 a barrel in less than five years. Airlines will make record proffits. If you watch the trend after the oil crisis of the 70's this is exactly what happened in the 80's into the 90's. The combination of Alternative fuels, new oil sources outside of OPEC's grasp being utilized, fuel efficient alternatives, lifestyle changes will not have a instant change in the economy. The displacement will be slow but's it's inertia will last for at least 15 years.
