If you aren't flying on reserve....and pick up something on a day off it counts above your guarantee. Meaning you might only fly 40-50 hours on reserve and pick up a turn or trip to get extra pay. Might be completely different in the summer..or at another base when they are flying guys on reserve up to 79 hours every month. But in slow months.....where you might fly two trips....it would be an easy way to get some extra $$$ if you were so inclined.

And correct me if I"m wrong....but the only limitation on Pilot to Pilot is FAR 117 rules right? Meaning the company Max credit time doesn't apply right? Open time pick up and trading IS constrained by the Company monthly max right?
