Unlike leisure travelers, business travelers tend to be all of the following EXCEPT

The characteristic of being "older" is not typically associated with business travelers when compared to leisure travelers. Business travelers often include a significant number of younger professionals, particularly those who are early in their careers and actively networking or attending conferences.

In contrast, leisure travelers can span a wide range of age groups, including families and retirees. Business travelers also tend to have more rigid and structured schedules compared to leisure travelers, who may have the flexibility to change their plans or explore spontaneous activities. This is evident in the fact that business trips are often planned well in advance to accommodate meetings and conferences, making them more scheduled and less spontaneous in nature.

Thus, the distinction that business travelers are generally "younger," "more scheduled," and "less spontaneous" reflects their travel patterns and the nature of their trips, while the notion of them being "older" does not hold true in this context.
