I can only say that I have never and, never will fly a commercial flight using GA figures. And I know no one in the company who would and why would they??
Hi Vis, I suggest you may have been mistaken when you "recognised the passengers." It is within the rules to fly empty into and airfield GA and then operate commercially out.
Netjets always works within the rules of the INAC and I know that these differ a little from JAR ops but, it is all fully legal with the Portuguese regulations. Every country's regulations have some benefits; the UK FTLs are less restrictive that the INAC, it's swings and roundabouts.
Have a happy new year one and all!!
