The scan below is a case in point. It shows the cover of the March/April 1991 cover of Serendib. That was the magazine back when Sri Lankan Airlines was called Air Lanka. It is a bit interesting to see how air travel has changed during the last sixteen and a half years.
First, the inside cover relays lots of important information after the Ayubowan. The page tells where the washrooms were in the Tristar aircraft. I also says how smoking was prohibited when the "No Smoking" sign was on. It warns that passengers weren't allowed to operate portable radios or television sets; however, thankfully, calculators and heart pacemakers were permissible. On the other end of the articles, Rocky V, Lethal Weapon II, and Gene Wilder in Funny about Love were among the inflight movies mentioned. (It depended on the whether inbound or outbound as everybody on the flight watched the same one which was projected onto hide-away screens.)
No wonder why I keep such things! After a while, there's fascination in anything.
