Isquare, to my knowledge, internally TK has looked at this off and on since at least 2012, When I posted what I posted, it was accurate at the time, however I would strongly doubt that anyone at TK is is looking seriously at this at this moment as they have more important things to worry about, like hopefully getting their flights back in the air, and you know, all that Covid stuff. Incidentally LH has kicked the can down the road at least a year on all their plans, as they were silly to implement during Covid.
