EAA AirVenture Oshkosh twenty twenty-six and the ten days that turn a Wisconsin cornfield into the busiest airport on the planet

EAA AirVenture Oshkosh 2026 returns to Wittman Regional Airport (KOSH) in late July for ten days that transform a small Wisconsin airfield into the busiest airport on the planet. With roughly ten thousand aircraft, over half a million attendees, and programming that spans the entire history of powered flight, AirVenture is the single largest gathering of aviation enthusiasts in the world — and this year is shaping up to be one of the best.

What Makes AirVenture More Than an Airshow

Calling Oshkosh an airshow undersells it by an order of magnitude. Yes, there is an airshow — a spectacular one — but AirVenture is an immersive, multi-day convergence of every corner of aviation. Homebuilders, warbird restorers, airline pilots, astronauts, twelve-year-old future aviators, and mechanics elbow-deep in Continental radials all share the same grass.

Aircraft park wingtip to wingtip across massive camping areas. Pilots fly in from Alaska, Brazil, Germany, and everywhere in between. Tents go up next to Bonanzas. Campfires burn beside Van’s RVs. The flight line alone is a museum-quality walk through aviation history — brand new Cirrus SR22s parked across from a fully restored 1943 North American T-6 Texan, a homebuilt that took eleven years to construct, or a Lockheed P-38 Lightning sitting on the grass like it could scramble at a moment’s notice.

The Fisk Arrival: Flying Into Oshkosh

Flying into AirVenture is an experience unlike anything else in aviation. The Fisk VFR arrival procedure routes inbound traffic along a railroad track with aircraft stacked above, beside, and below. Tower controllers call aircraft by wing color — “Red and white Cessna, rock your wings” — then assign a runway. Pilots land on a dot painted on a grass strip with tight spacing ahead and behind.

It demands real stick-and-rudder skill, but thousands of pilots manage it every year, from students to airline captains. The EAA publishes the NOTAM weeks in advance. Study it. Watch YouTube videos from previous years. Brief it like an instrument approach — know the landmarks, the radio calls, and the go-around procedure.

Driving in works too, with massive parking lots and constant shuttle buses. But touching down on that grass runway, knowing you flew yourself to the biggest aviation event in the world, is something else entirely.

The Daily Airshow

The afternoon airshow runs roughly three hours of nonstop flying. While the full 2026 schedule has not been released, past lineups and EAA hints point to the usual headliners: the USAF Thunderbirds or Navy Blue Angels, warbird formations from groups like the Texas Flying Legends flying World War II fighters in tight formation, and aerobatic acts that redefine spatial orientation.

Wednesday and Saturday nights bring the night airshows — aircraft fitted with LED light systems fly aerobatic routines against the dark sky while pyrotechnics and fireworks go off. It is, without exaggeration, pure magic.

The Seaplane Base on Lake Winnebago

A dedicated seaplane area on Lake Winnebago operates as its own event within AirVenture. Floatplanes splash in and out all day — amphibious Cessnas, de Havilland Beavers, and the occasional turbine Otter. A Beaver on floats executing a step turn is one of the prettiest sights in aviation.

Forums, Workshops, and Presentations

The educational programming at AirVenture is world-class and often overlooked. The EAA runs workshops and presentations all day, every day in large open-air pavilions. Topics range from TIG welding for aircraft builders to tailwheel transition training to talks by actual astronauts describing orbital perspectives on Earth. Walk outside afterward and someone is doing a knife-edge pass in a Pitts Special at two hundred feet. The contrast is part of the charm.

The Vendor Area and Experimental Showcase

The vendor area alone takes two full days to cover properly. Hundreds of booths represent every avionics manufacturer, headset company, and flight school in the industry. The experimental aircraft area is where the energy runs highest — jet-powered gliders, glass-cockpit gyroplanes, two-seat electric trainers built by startups in Oregon. Many exhibitors let attendees sit in cockpits of aircraft that haven’t even been certified yet.

What’s New for 2026

Several trends make 2026 a particularly compelling year:

The homebuilt movement is surging. With MOSAIC rule changes reshaping the light sport aircraft category, the experimental community is buzzing with new designs, new powerplants, and electric hybrid concepts that make practical sense. Expect fresh airframes and lively conversations on the show floor.

Affordable glass cockpits are accelerating. Companies like Dynon, uAvionix, and Avidyne are producing avionics that put experimental aircraft panels on par with factory-new certified aircraft — at a fraction of the cost.

The warbird community is having a moment. Long-running restorations are reaching completion, and rare types not seen flying in decades may make appearances. The rumor mill is already active, and early hints suggest some genuinely surprising arrivals.

Camping at Oshkosh

Camping under the wing of your airplane is an Oshkosh tradition. The EAA offers camping areas for fly-in aircraft, drive-in visitors, and everything in between. Camp Scholler functions as a small city with shower facilities, bus routes, and a general store. Theme camps and pilot groups claim the same patch of grass year after year. The friendships formed at Oshkosh tend to last — people return every July for decades.

Planning Your Visit

If you can only go one day, choose a Saturday for the biggest crowd and the most packed airshow lineup. Three days is better — use a weekday for forums and flight-line walking when crowds are thinner, then a weekend day for the full airshow. All ten days is the dream, and regulars who take their entire vacation for Oshkosh will tell you it’s still not enough.

Practical notes: bring good shoes. You will walk more miles than you expect. Bring your appetite — this is Wisconsin, so fresh cheese curds and bratwurst are everywhere, and there’s a pulled pork stand near the north end that earns a devoted following.

The Experimental Aircraft Association (EAA) has run AirVenture at Oshkosh since 1970, when the event moved from Rockford, Illinois. It has grown every year since. Full scheduling details are available at eaa.org.

Key Takeaways

• EAA AirVenture Oshkosh 2026 runs for ten days in late July at Wittman Regional Airport, drawing ten thousand aircraft and over half a million people
• The Fisk VFR arrival is demanding but manageable with preparation — study the NOTAM and brief it like an instrument approach
• 2026 highlights include surging homebuilt activity driven by MOSAIC changes, advancing affordable glass cockpit avionics, and rare warbird restorations reaching flyable status
• Plan for at least three days to cover the airshow, forums, vendor area, and flight line — one day is not enough
• The community and atmosphere are the real draw — this is where every corner of aviation meets on the same grass
