The message line includes a list of DPs which were flown this week with a link you can click on to see the pairing. Is that enough?
I have talked DPs at both meetings I've had in MEM, and will continue to work with folks explaining why its important. I'll also include that info in my block letters. However--do you really think folks are picking them up not KNOWING its wrong?
Again--I KNOW it sounds like a cop out--but YOU GUYS have to be disgruntled voices in your crewmembers ears...
