For example, the airline industry is a fairly cyclical industry; in good economic times, people have more disposable income and, therefore, they are more willing to take vacations and make use of air travel.
Conversely, during bad economic times, people are much more cautious about spending. As a result, they tend to take more conservative vacations closer to home (if they go at all) and avoid expensive air travel.
Corporate lending tends to be concentrated on a few highly cyclical industries, such as energy and property.
