PM me the pilots name. I will contact him and we will get the flight info. The jumpseat pilot will be fired if what you say is true. There was no program such as this so clearly he was operating outside of Delta. All management riders at Delta are required to identify themselves and state exactly why they are riding on the jumpseat. Even a check Airman just catching a ride to work or for personal reasons on the jumpseat must identify himself to the crew as a check airman.
Pilots who were assisting on the transpac spin up used the TOE guide. They took notes on areas where there may be differences between NW and Delta and implimentation. Non jeopardy and notes never attached with a flight or crew. Every pilot doing that program (set up by the 767 program manager a NW pilot) had to identify himself to the crew and why he was there. He was required to show up for the briefing and not just as a jumpseat rider at the gate.
Your story was also posted almost word for word in the Dalpa forum yet no one was ever able to attach a date or crew to the rumor. I really personally find it hard to believe that pilots search other pilots stuff when they go to the bathroom. Been here a long time and have never seen that one!
