If you want to see something really fun check out the open time at places like Skywest, Air Whiskey, or Republic. Over there a 20 hour four day is a crap trip, and 24-25 hour four days are a dime a dozen.
It's no wonder my friend who is a bypassing First Officer (because they don't need to force upgrades) at Skywest is making easily more than me as a reserve Captain at PSA.
