I'll agree that some of the jokes are dated - you can't smoke on airplanes anymore, but the idea that most of the jokes are dated?

Shirley you can't be serious? The word play and visual comedy in the movie is classic. The Roger/Clarance/Ouver take-off sequence, Leslie Neilsens deadpan "Dinner was the chicken or the fish? - yes I remember, I had the lasagne", the guy waiting in the taxi, "everything is ok" as the pilots are dragged down the corridor, Stiker being stationed outside of Drambuie. Hell I think Airplane has the first dramatic double-sunglassed removal.

There is so much clean, zany humour in that movie - the idea that you can claim classic, surrealist comedy is dated makes me question whether you believe that statement at all.

One that always gets me and is timeless, when the flight attendant hits everybody with the guitar when bringing it forward.

You ask someone else upthread when they last saw the movie. No offense but when was the last time you saw it? Very few jokes haven't aged well unless you just stopped liking puns and dad jokes, which would be a You thing, not a movie thing.

A small portion of the jokes make less sense out of their time, but you’re perhaps too hung up on the movie having “aged well.” People age a lot more than movies do. There were middle aged people just like yourself unimpressed by the constant idiocy of Airplane’s humor four decades ago, also nonplussed by how funny others found the film.
