Where is anyone coming up with .10 an hour less in per diem? Considering AA,AK,B6,DL,FX,NK,SWA,UA, and UPS Frontier pilots are earning .34 less an hour than the average. At 4-4 day trips a month it equates to hundreds of thousands of dollars when invested monthly over a 30-year career.
Obviously one uses their per diem to cover expenses and therefore wouldn't be investing all of it, but it's all money-in / money-out and it's not an insignificant amount of money although it might appear that way on the surface.
Plus, it's an extreme outlier for a new contract. There's at least one regional that pays more per diem than F9. It's so far outside of the realm of reasonableness that it NEVER should've been agreed to.
