💡 Connection Tips
Wittman Regional Airport (OSH) is world-famous as the home of the EAA AirVenture Oshkosh fly-in. During the annual event in July, it becomes the world's busiest airport. Ground transport is exceptionally well-organized during AirVenture, with dedicated shuttle buses running to local hotels and campgrounds.
Outside of the event, transport is limited; car rental agencies (Enterprise, Hertz) have desks on-site and are the best way to reach downtown Oshkosh. Local taxis can be called from town (approx. 10 mins away) Wittman Regional is busiest when EAA AirVenture changes the whole character of the airport, so the ground plan can shift dramatically in summer.
The airport handles NO scheduled commercial airline flights; for commercial travel, use Appleton International (ATW) or Milwaukee (MKE). At 809 feet elevation covering 1,392 acres, the airport operates four paved runways including the main 8,002-foot runway (18/36), a 6,179-foot crosswind runway (9/27), and two shorter runways for smaller aircraft, along with a high-quality terminal building serving as a major hub for general aviation and corporate charters.A hotel or car rental is the normal plan outside AirVenture, because the shuttle system is event-specific and the summer crowd can change how easy the curbside pickup feels for everyone there. most days
