OK, let me show you the math then:
USD 53 per hour (1-60 hours block)
USD 62 per hour (61 hours and above)
So on 85 hours "productivity pay" (aka "flight pay") the total is:
$4730 US (this is tax free)
$3000 US base pay (taxed)
----------
$7730 Sub Total
$ 140 "check in allowance" (transportation)
---------
$7870 TOTAL
There is also field reserve pay that can figure into the amount, and also remember we are converting to US dollars.
