Yes, the last routes to go, on All Fools Day 1998, was Tokyo. Virgin stopped on the same day. The smoking ban was phased in, starting with Domestic.

I remember a Paris flight when I was a kid and my parents going to some lengths at checkin to ensure we were in the non smoking section. Well we were, but the smokers were in the row behind, no curtain. The tradition was in those days people put their cigarettes in their mouths at take off, and then lit them when the undercarriage retracted. The bing sound, still there, was the sign to light up. Never been so sick on an aircraft before or since!
