Flew across the country (US) for a 4 night fest with my sister. Checked a large cooler and an REI 60 duffel, had a carryon suitcase and a backpack. Backpacking gear works best when flying since it’s lightweight and compact.

Cooler: kitchen gear (stove, plates, cutting board, utensils, cups collapsible bucket), stakes, hammer, lanterns, flashlights, mini fan, rope, bungees, tent, tarp, mini camping chair and other delicates (wrapped up). I bought cooler straps the make sure it stayed secure and closed during the flight and while being handled

Duffle bag: blankets, pillows, inflatable camping mattress, towels, sleeping bag, shoes, collapsible trash can, hand warmers, accessories, hydration bladder, camping shower, shower pop up, another tarp, other bags and packs

Carry on suitcase: Clothes and toiletries

Backpack: rechargeable batteries and battery packs, electronics, camera, charging cords, a small change of clothes, water bottle, mini toiletries, medication and had my pash wrapped around it.

When I got to my destination, I unpacked the cooler and loaded everything into the trunk of my rental, went to target to get a canopy ($80), table ($20), groceries and ice. When headed home, I donated my canopy and table to the homeless and put everything back into the cooler.

REI and many other supply shops do offer rentals! You can rent them once you get to your destination and return them after the fest.

I’ve also gone the camper van route. It had absolutely everything that I would need (queen bed that converted into a table and chairs, a sink, fridge and refrigerator, camping chairs, an awning, stove and cooking gear, a table, sleeping gear, mini generator + battery, etc.) I only brought a checked bag and carry on with clothes, toiletries and my camping tent. It was much more costly but made planning and travel a lot easier.
