What did people do when flying in, say, the 60s, 70s, 80s, 90s. . .etc?

And making ‘just’ a few rows peanut free is control and will result in the entire aircraft being peanut free. The airlines can’t risk a stewardess making a mistake and giving the darling a peanut.
To be clear, since you missed it: “What did people do ABOUT PEANUT ALLERGIES when flying in, say, the 60s, 70s, 80s, 90s. . .etc?”
