Upper Deck Windows Of JAL 747-100

Fri May 16, 2003 2:32 am

In the early time, JAL's 747-100 has only 3 windows on the upper deck.
But in late 1980s', it added more windows to some of the upper deck of 747-100. Why did JAL do so?
It makes me confuse in distinguishing JAL's 747-100 and 747-200!

I'm pretty sure that it was due to the seating configuration. When the 747 was introduced, they were often made with lounges on the upper deck. But, once the demand for more seats rose, they outfitted the upper deck with a regular seating configuration. So, they also added more windows for each seat. Hope I was of some help. Smile/happy/getting dizzy

Also note that JAL got 747-SR's starting in 1973, which were based on the 100 with strengthened landing gear, wing slins etc and had a fullset of upper deck windows as opposed to the three in the -146's as no lounge was fitted.

JAL also has 747-146(EUD) that appear to be 747-346 to casual observers. (Like me).

Your observation is right and wrong at the same time. Boeing made the 10 window upperdeck available for all 747 variants from 1971 onwards (first aircraft was the first Qantas 747-238B). Until then all had 3 windows there.
JAL 747s delivered after 1971 all had the 10 window standard from the beginning, only that (similarly to TWA) 7 of these 10 were plugged to match the 3 window look. You cannot see that on most pictures.

But you can see it here on JA8107 in pictures from 1972, 1986 (7 plugged windows clearly visible) and 1991.
