Pat chicken wings completely dry with paper towels. Lay them out on a wire rack set over a sheet pan.
Sprinkle baking soda evenly over all wings. Toss and massage with hands to coat every piece. Surface will become slightly tacky.
Place rack uncovered in refrigerator for minimum 30 minutes, ideally 2 to 4 hours.
Remove wings from fridge and let sit at room temperature for 15 to 20 minutes.
Preheat air fryer to 400°F (204°C) for 5 minutes.
In a large mixing bowl, combine kosher salt, garlic powder, smoked paprika, and cracked black pepper. Add wings and drizzle with avocado oil. Toss until evenly coated.
Arrange wings in air fryer basket in a single layer with small gaps between each piece. Do not overcrowd.
Air fry at 400°F (204°C) for 12 minutes without opening the basket.
Open basket and flip each wing using tongs.
Cook for an additional 10 to 12 minutes until wings reach 190°F (88°C) internal temperature and skin is deep golden-brown with bubbled, cratered texture.
For buffalo wings: Melt butter in a microwave-safe bowl and whisk in Frank's RedHot until smooth. Transfer cooked wings to a large bowl, pour sauce over, and toss to coat.
Plate immediately, garnish with fresh parsley, and serve with celery sticks and blue cheese dressing if desired.
