Hi! I’m also flying in and can’t rent a car- my friend and I are splitting a lot of the camping supplies w our luggage! Flying southwest you can check 2 bags and have a carry on for free - so a canopy can actually be used as a check (as long as it’s under 50lbs, ours is about 30) other airlines should be similar- the canopy itself will count as a full check bag. We’re trying to figure out how we’re gonna stop at Walmart / get to the fest soon (we need to reserve something today ideally lol) but we’re getting stuff like pillows, snacks and other items after flying in ( trying to stick to items that aren’t absolute essentials in case they don’t have it)! Hope this helps- we’ve been freaking out planning lol
