There are two distinct types of operation being discussed in parallel here, which is causing some of the disagreement.
1 -- Long haul. Carrying extra fuel creates a vicious circle. To carry fuel increases fuel burn to the extent that it becomes necessary to carry even more fuel to compensate and restricts pax/cargo loads. Cost escalates rapidly.
2 -- Short haul. Carrying extra fuel is usually a relatively minor problem with respect to pax/cargo and cost. Frequent sectors and business style pax demand low diversion frequencies as a high priority.
Make sense ?
PS. -- BOAC, no offence intended. I did'nt mean that your post did'nt matter, I meant that it did'nt matter that EDDNR thought that I was referring to his post ........ if you see what I mean.
