Casa needs to take a very close look at the fuel policies of these operators.This is a 3rd world operation with unreliable wx forecasts and navigation facilities.The PIC is on his own!!The 737-200 is a very marginal operation on HIR.Don't know about the E170 but you need a genuine alternate and fuel to get there.If that means sacrificing payload to carry the PIC's minimum fuel effecting profit margins YOUR COMMERCIAL DEPARTMENT HAS THE WRONG AIRCRAFT.
