Yep. They do go senior. The allure of being home all day, every day, is pretty strong. And some are willing to compromise safety in order to do it.

"Stand ups" have always been a way to get around the FAR rest requirements. Nobody sleeps during the day and then stays up all night during a stand up. The reality of it is that the flight is done late at night with a crew that has been up all day and is nearing the point where they should call it a day and go to bed. And then the flight the next morning is done by that same crew after they got maybe 5 hours of sleep. It's unsafe. They should have fixed this loophole in FAR 117. If DALPA allows this to be added to our contract, there's no way they can tout a motto like "schedule with safety" with a straight face.
