Pan Am: No Sex Please. We're Flight Attendants by Jon Breakfield (2016) (**)
This book is not just a laugh-out-loud romp around the world or a historical foray into the beginnings of the great airline nor is it an emotional unveiling of the Facts and the Fun behind the logo...it’s all of the above.
"Pan Am was an education. It was our graduate degree in foreign languages, sociology, psychology, culture and etiquette."
