Sami,
In addition to the economics of the oil crisis (high oil), you can now tie this event to other effects. Since were able to data check all airports, I am finding that several airports were closed down due to the downward pressure that high oil cost brought upon.
So moving forward, you can now remake the event too include high oil costs, reduction of pax and airport closures. Something like:
Oil Crisis of 1970s:
Due to growing geopolitics issues, oil as a commodity is being heavily effected. The effects of this event are expected to drag on for years, analyst at major firms fear.
Some effects to expect are:
Unpredictable spikes in oil
Lower Global passenger travel
Closure of airports
This event can become something that rivals 9/11 in terms of effecting the airline industry.
