"I feel about airplanes the way I feel about diets. It seems to me that they are wonderful things for other people to go on"

This quote by Jean Kerr is a funny way of revealing her opinion on aircrafts and diet plans. She is suggesting that she does not personally find either of them to be particularly attractive, but she acknowledges that they can be useful for other people. This might be analyzed as her being content with her own way of life and not feeling the requirement to make any drastic modifications. She is also recommending that she is open-minded and accepting of other people's choices, even if they are not her own. This quote is a terrific tip that everybody has various preferences which it is essential to appreciate those distinctions.
