Cost Index is Bull!!!!?
I have a concern on cost index:
the cost index calculation must consider the fuel costs and the time costs, right?
The time costs are, among many, crew and maintenance, as engines overhauls etc.
But how to calculate the cost of an overhaul that will happen many months ahead? I say this because I don't live in US, and my currency is not fixed to the dollar. The parts costs are fixed in dollars, because they are imported from US or EU, so the exact cost of an overhaul is unpredictable.
If the brazilian currency, the REAL, fluctuates, the schedule maintenance costs will change, in a manner I can't predict. So, in my case, Cost Index is bull!!!!.
