Those numbers are off. SWA = $183. UPS = $186. Plus, the number of hours in the guarantee have nothing really do to with the hourly rate -- except in the case of premium pay like JB.

The way I got UPS #'s are as followed.
hourly rate $186
Min Guarantee 81 Hours
186 multiplied by 81 divided by 70 = $215.22
since every airline have a different way of calculating pilot salary, I chose 70 as a way of standardization. we are talking about the minimum amout of money that pilots will make without going into the premium pay.
