I was nervous the first time I flew on a commercial airline. I grew up in a non-flying family – ironically in the state where the license plate contains the slogan ‘First in Flight’ – so when I had the opportunity to fly I was both excited and nervous. My excitement was for the experience itself. The nervousness included a concern about landing the hard way and about air travel etiquette. How was one to behave in an airplane? What was the dress code?
