At DAL we kind of have a partial variation of that. They call it "credit surfing", and what you do is use the swap with the pot function (swap with open time) to dump your regular trips for broken trips that start to show up around 48 hours prior to report time. They usually have a fly 1 or 2 legs, and then DH back the 2nd day. You wind up with a lot of credit, not much block, and you can pick up premium after that because you won't have any FAR limitations.

There's also "Rolling Thunder" on reserve. You bid a bunch of days off in a row at the beginning of the month. Then you "green slip", which for reserve pilots is working on a day off and pays above the guarantee and you get your day off back (kinda, it's more complicated than that). The end result is you fly over what were your off days, all over guarantee, then at the end of your off days, you've got a bunch of days off coming back to you, and so you sit the rest of the month. Done right, you can also pocket the added days off as "payback days", which are very, very powerful if used right. Net result is everything you do is above guarantee for the same amount of work. Guys and gals can kill it that way, and then simply coast a few months by dropping to zero, or close to it. Between personal drops and APDs & IVDs (trip drops with a silver bullet), you can clear out your schedule biggly.

Same kind of thing here. Folks who are dialed into the system really can work it, and they're very, very sensitive to any changes. You don't have to be super senior, though, to make it work. Even junior folks can kill it.
