I guess my pilot group is a bunch of rebels but years ago guys just quit wearing the hats en masse and they finally did away with the "requirement" to wear it. I think it makes a difference if you're a freight dawg, too. We don't see the public while at work. Some guys do still wear the cap, and more power too them, but it should have been optional from beginning. I'm a big believer in carrying around as little as humanly possible between hotels. I like the leather jacket cause I can wear it at work, then take the stripes off, and wear it walking around outside on layovers. No need to carry around an extra jacket.
