Classical widebody first class

[chornedsnorkack]

People are praising classical flying. What is there to praise?

See

Tristar 500 standard arrangement is first class seating at 6 abreast and 42 inches pitch.

42 inches pitch is not first class, nor business class. It is premium economy (although 6 abreast is good for premium economy). Looking at other classical planes like 747SP, DC-10, 747-200 et cetera, the picture is the same: 6 abreast 2-2-2 seating, and 42 inches pitch or less.

I cannot see a technical reason why a 747SP should not have been fitted out with 100 flat beds, like Singapore A340-500. But what was the reason that it was not done? There must have been some sort of reason...
