Any specific behavioral examples that makes a captain "undesirable"? My bigger beef is how the other pilot treats everybody outside of the cockpit. My biggest concern was when a captain whispered sweet nothings to his(could be her, just not my experience) wife(or husband as far as I know) on the phone, was always considerate to other pilots, but was an ******* to the cabin and/or ground crew when stressed. Made me wonder how that person would react if stressed in flight...
