Bally,
I did the charter thing too (Airworld, Flying Colours, JMC, Apple Vacations) and the charter company's know their flying schedule much further in advance than the scheduled airlines do. Yet they are chronically incapable of scheduling a pissup in a brewery...
The flights are set years in advance. There is never a change of guage so why can't they schedule? They should hand you your schedule the day you are hired for the next decade or so <G>....
As near as I can figure, the deliberately screw up the scheduling so pilots can get in an uproar and than they can say they fixed something. Funny thing though, they never actually get around to fixing it.
I have a theory about drug testing of pilots. I suspect that drug testing was implemented to make sure that the pilots never got the big picture, becuase they must be smoking something illegal up in management...
Cheers
Wino
