People who are too young or, frankly, not thinking hard enough really do romanticise what the world was like when people could smoke fucking everywhere because people really did smoke fucking everywhere. Restaurants and pubs had a visible smog in the air, the odor permiated all flavours and everything was slightly sticky unless it was wiped clean a few minutes before. Being trapped on a bus with a bunch of smokers was nightmarish enough, but being at the back of a plane - the cheap seats - where air was very, very slowly circulated front to back was hell, especially for asthmatics.
