140k for 6 year 767 CA seems optimistic to me. That assumes a monthly credit of 77.7 hours, so to do that on would have to A) not conflict any vacation or training or call in sick, or B)work overtime.
3 vacation weeks drop you to 62 hr guarantee
A sick call drops you to guarantee
A training event that is not worked on days off drops you to guarantee.
I know some people here dont like my data but its not a matter of opinion, its the embarrassing facts, on 6 year pay, a 767 capt who maximizes 3 vac weeks, conflicts training, and calls in sick once will be more in the $126,000 range.
I calculate this based on 6 months at guarantee and 6 at 78 hrs. I feel based on my experience here I am even being optimistic in my numbers but I am sure others are less motivated to conflict training etc. For me 17 days is enough. I am unwilling to do my training on days off and I take my vacation.
