So if I understand you both correctly, in those two places the self-check-in kiosk is integrated to the bag drop off belt, and as you check-in, you put the bags on the weighing belt and it weighs it and prints out the baggage tags. At least that means you only have to queue up once for check-in rather than twice in my case. I assume that there will also be some standalone check-in kiosks for people with no hold luggage?
I don't think the problem will be fixed by a new generation of passengers if my assumption that a significant number of long haul overseas travellers fly infrequently is true. I do think that within the next 20 years, robotics and A.I. will probably solve this with kerbside valet. Before that, we may have within the next 5 to 10 years, an airline virtual valet augmented reality app that tracks our location and directs us to the services points with explicit step-by-step instructions. Still beats the confused state I was in last trip.
