I have had FReepers of a bit older age tell me that the “Dear Penthouse” stories in fact happened in the “gogo” days of stewardesses who were looking for fun in the air.
Never happened to me but I didn’t start flying regularly until the 90s.
But I do recall the airlines shamelessly pushed the sex appeal. And many Asian airlines still do in their native countries, where they are allowed to hire based on looks (ah the good old days).
Flying was more expensive and exclusive.
If you were flying First Class in the 60’s and 70’s you were very well off or high enough in your corporate infrastructure and would get phone numbers especially if there was no wedding band.
Today it’s more like Greyhound...
