Before I went to pax hauling I flew freight as a feeder to UPS, DHL, ABEX, etc., and I echo the comments that there are many benefits that are overlooked. Here's one I just learned that is causing me to give consideration to go back to freight: security checks. Removing my shoes, watch, cell phone battery from the phone, laptop computer, change, etc. only to turn around and set off the scanner and have to be wanded, frisked (oh, that felt good), and de-belted. It feels good to be so trusted to an airliner full of passengers.
