Most of the mishmash trips offered now go 180 degrees against that. Then people scratch their heads wondering why pilots are getting sick, fat and fatigued. Btw, screwing with your circadian rhythm also causes your body to release increased cortisol leading to more fat storage among other things.

Does anybody know if ALPA is/has or is going to push for more consistent circadian agreeable schedules? I know that companies will say they can't afford it and will go out of business when in fact they would just need to hire 10% more pilots and would still be minting money. This is a serious issue that affects every pilot, during their career and also after they retire when much of the damage cannot be undone.
