I traveled on a airline 4 times a year to visit my grandparents in the 70s .
I wore a coat and tie on all flights .
People on the plane were polite and reserved .
My father said it was one of the few places they never worried about me .
Then Peoples express began the rapid descent to hell flights .
That scenario is repeated daily on thousands of flights around world - charter flights on smaller jets.
Was the golden age of travel when airfare was too expensive for most people? Absolutely.
