Does anyone know why this 747 seems to have Door 3R blocked off? If it did, was there a seating capacity limit on this aircraft?

The overwing exits can be blocked and have been so by several operators including BA, KLM as I recall.

More seats = more $$$$

As I recall sometime in the late 80s, some rules changed in Europe that allowed for airlines to block off overwing exits on the then (classic) 747s.

But more seats would mean more exits necessary. Blocking off exits would reduce the number of seats permissable on board.

Quoting CallBell (Thread starter):

That aircraft was leased from BA. A few 741/742/743 operators including BA, KL and CX (they were possibly the only ones, not sure) had the overwing #3 door exits deactivated sometime in the early 1980s or thereabouts. In the cabin they were panelled over with standard wall panels and several additional rows of seats were installed in those areas, although some lacked windows. I recally flying on BA and KL 747s after those exits had been sealed off.

While the change apparently met certification requirements for evacuation, it was controversial among air safety experts since it obviously meant a much longer distance to the nearest exit for quite a few passengers, especially when combined with the increased number of seats.

Photos below of BA/KL/CX aircraft after the #3 exits were deactivated and the door outlines deleted.
