Those L1011 Tri-Stars were still around in the early 90s. I flew them to regional destinations in Asia when I was working in H.K. during that period.

IIRC, I may even have flown them to Beijing. That was before CX ceded the China market to then fledgling Dragonair, in exchange for some ownership and I believe management supervision of KA. Boy, was that a mistake or what! CX is just now inching its way back into the lucrative China market.
