JayAre, let me try it one more time
All of this is about SkyWest, I know ExpressJet also has good if not better set up.
The time limits mentioned above are the actual flight time limits or block time.
The time you get paid is a bit more and called credit time.
So for example imagine a 1 hour scheduled flight (block) flying which you get paid 1:07 (credit). If you over fly that leg - actual time will be paid.
That data comes from bid packeges - published and given to crewmembers options of schedules (lines) for bidding.
Anyway the bottom line: You might fly 82 (example again) hour line and put 82 hours in your logbook but make money for 85 hours. In Feb. I have scheduled block of 102 hours (below my 120 limit) and get paid for 115.
If you are on reserve and fly less than 75 hours credit - your pay check still will be at 75.
Hope this helps
