It goes both ways for sure and generally depends on how much flying there is to be had.

You can -
Fly your line and get around 100 a month.
Try to give away or elitt down and work less and make less.
Fly your ass off and get a lot more.
Try to clear as much of your board as possible and fly smart and either make a lot of money or have a lot of time off.

I have done all 4 depending on the month. This month, I have found that the open time and reroutes have been scarce so I am working more to pay for a vacation that I have upcoming. July I worked 12 days and still killed it. I agree that it is frustrating at times, and there are things in the contract and in the AIP bullet points that frustrate me as well. I want to be treated like a professional and I find that is lacking here by the way ground ops treats us and the way we negotiate our contracts.
It's Southwest, not United, not Delta. We do have a lot of flexibility in our schedule and that is the big advantage to working here. There are, however, huge trade offs to that.
