Keep in mind that at NWA the CA never did the walk around(when I got hired the only person qualified to on the 727 was the FE and the first flight of the day the FE pre-flighted both the CA's and FO's sides of the cockpit. They drank coffee, read the USA Today and Bs'd with the FA's). Wasn't their job. Speaking for myself only, when the merger happened, I was told by FO's that at Delta the CA did, my replay was "yea right". I've since learned to embrace the walk around as the longer I stay gone, the more gets done, like everything Just remember it's still the FO's job. We have had lots of complaints of the assumption that walk arounds will be shared.
