Some airshows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers. Many air shows are held in support of local, national or military charities. [[Military]] air firms often organise air shows at military airfields as a public relations exercise to thank the local community, promote military careers and raise the profile of the military.

Air "seasons" vary around the world. The [[United States]] enjoys a long season that generally runs from March to November, covering the spring, summer, and fall seasons. Other countries often have much shorter seasons. In [[Japan]] air shows are generally events held at [[Japan Air Self-Defense Force]] bases regularly throughout the year. The [[Europe]]an season usually starts in late April or Early May and is usually over by mid October. The [[Middle East]], [[Australia]], and [[New Zealand]] hold their events between January and March. However, for many acts, the "off-season" does not mean a period of inactivity; pilots and performers use this time for maintenance and practice.

The type of displays seen at shows are constrained by a number of factors, including the weather and visibility. Most aviation authorities now publish rules and guidance on minimum display heights and criteria for differing conditions. In addition to the weather, pilots and organizers must also consider local airspace restrictions. Most exhibitors will plan "full", "rolling" and "flat" display for varying weather and airspace conditions.

The types of shows vary greatly. Some are large scale military events with large flying displays and ground exhibitions while others held at small local airstrips can often feature just one or two hours of flying with just a few [[:wikt:stall|stall]]s on the ground. Air displays can be held during day or night with the latter becoming increasingly popular. Air shows often, but do not always, take place over airfields; some have been held over the grounds of stately homes or castles and over the sea at coastal resorts.

The first public international airshow, at which many types of aircraft were displayed and flown, was the [[Grande Semaine d'Aviation de la Champagne]], held Aug. 22–29, 1909 in [[Reims]]. This had been preceded by what may have been the first ever gathering of enthusiasts, June 28 – July 19 of the same year at the airfield at [[La Brayelle Airfield|La Brayelle]], near [[Douai]].
