When I first moved to Jakarta, BA flew 033/034 LHR - KUL - CGK return, and I used them a few times for home leaves.
The upper deck of the 744s then (95-96) had a swimming pool, nightclub and a casino, which they had to close when flying over Saudi airspace as their Shariah Laws forbade gambling.
The flooring was blue shagpile carpet, while the walls and ceilings were in an off-white shagpile as well, I assumed at the time this helped with the sound insulation.
Clothing was optional for us SLF, and there was a minimum alcohol intake of 3 bottles of Krug (or equivalent). Happy days.
