Jet set is a term used to describe an international social group of wealthy people, who organize and participate in social activities all around the world which are unreachable to ordinary people. The term comes from the wealthy people with the lifestyle of travelling from one classy or exotic place to another via jet airplanes.

A minor connotation attributes jet set to traveling salesmen who live their lives largely flying in jet airplanes. Due to common accommodation in airport hotels it happens that many people know each other. In some parts they lose their original roots building an international social group and organazing their own social activities which happen all around the world. Traveling salesmen usually have high income and good links to the wealthy people.
