Very interesting article. and I can see the concept. Re your 2nd paragraph, when you have crews only qualified on particular aircraft, when there is an A/C change, and you have a crew on a night-stop layover, not qualified to fly the return flt, it leads to problems. I saw this with AC in the 70s & 80s, and crew stuck in foreign countries waiting for an aircraft on which they were qualified to return to home base. Pilots and Cabin crew were both affected.
However, it does identify those who are “Not doing their job properly”.
Good luck with the 787!
