It's is brave the captain had the courage to speak up. Delta should just let him finish out his time and then retire and LEAVE HIM ALONE.
WOuld Delta had preferred the captain to pass out over the Pacific?
One of my first flights on American -- we were flying around for six hours over Pittsburgh and then landed then the crew said "Our contract says we worked passed the number of hours to be considered in healthy and safe order." So the passengers were grounded.
Initially I was furious but after learning of what could happen maybe I should have been thankful.
I notice also on some of teh U-A pacific flights the crew sleeps in a section between business and coach with big signs saying "Crew resting, be quiet or talk low." Of course most passengers ignore it.
