My last 3 tours I averaged 15.9 hours.

15.9-12.1=3.8
3.8x118=$448.40

Did I mention they were 8-day tours?
And these numbers are historical. After scheduling is taught to work the system, and the financially desperate pilots start bending over for extra $, these flight time numbers will drop. The company knew this. So for insurance, to pass this TA in case the pilots figured this out in time to vote NO, they threw in the bonus.
This TA will pass because of 2 groups of people. The sellouts grabbing their 30k bonus. And the idiots who drank the kool-aid of “$50k+ raise!!!!!”
