The finest rides I ever had were with 747's from Cargolux.
(I used to fly as a horse-escort Iceland-Luxembourg)
So, cargo bay full of goods, and up to maybe 30 horses, you go up to the "bubble" by a ladder, and up there are really big seats, and cabins to sleep in as well as a little kitchen, and the cockpit was open, so you could go in and have a chat with the skipper on the cruise.
Wonderful, - but those days are gone....
Chairs were almost lazy-boy quality...serious!!!
