Cuting or no cutting, I wonder why anybody flying in J or F wants to board an aircraft early. I can understand it in Y with all the overhead luggage constraints, but J and F? In any case, if I'm travelling Y even holding MPC "master of the universe" status, I don't mind letting J and F pax first, after all they are paying much more than I do, right?

Now turning into the heart of the subject:

KA is a saviour when travelling to Mordor.
It's like a warriors wife, preparing her husband's armour and giving him a few hours respite before the battle, and welcoming him back home afterwards, to a clean, comfy, and relaxing nest to give him cure to his wounds.
Something like the last helicopter from Saigon or a modern Crimean Nightingale.
No more can be said.
