That sounds pretty far fetched considering what would have to be programmed and updated whenever a pilot moves or changes status. Makes a nice conspiracy theory though.

I have heard this kind of thing many times over the years, pilots who add more fuel by base, pilots who fly faster by age, gender, geographic location, commuter status,etc.... What I have never heard in all those years is a pilot being disciplined for any of the rumored fuel, flight time, burn actions.

I think the dispatchers have more than enough on their plates as it is. I know a couple and will ask them next time I have occasion to speak with them.
