CargoOne,
Agree 100% with you......
But I do not think you can equate a mechanical failure with a failure in communication from the outset.
Of course the boss is going to be p**sed if you tell him that you can not perform the flights that the salesman told him was easily achieved.
And rightly so!!
My point was that if the boss had already been told, from the start, that if he wants to go to NZ, then there were certain factors to be taken into account, like tech stops, crew change etc, then he would not have the right to be upset.
Doesn't mean he wouldn't be when it happens
