In a small mixing bowl, whisk together the buttermilk (1 cup), vegetable oil (2 tablespoons), honey (2 teaspoons), garlic (1 large), 1 1/2 teaspoons salt, and 1/2 teaspoon pepper. Place chicken pieces in a 1-gallon resealable plastic bag and pour buttermilk over the chicken. Press out as much air as possible and seal bags. Place on a rimmed dish or plate in case the bag leaks. Refrigerate overnight for up to 2 days. Flip the bag halfway through marinating time.
Take the chicken out of the ziplock bags and place it on a wire rack so any extra marinade will drip off.
In a shallow bowl whisk together flour (1 cup), seasoned salt (1 tablespoon), and 1/4 teaspoon black pepper.
Dredge the chicken pieces in the flour mixture, shaking off excess, dip into the egg (1), then dip again into the flour mixture, shaking off excess. Place coated pieces on a piece of foil. Mist the chicken with vegetable oil.
Preheat the air fryer to 390ºF (199ºC) for 5 minutes.
Place coated pieces of chicken in a single layer on the bottom of the air fryer. Set the air fryer to 390ºF (199ºC) for 18-30 minutes (depending on the size of the chicken pieces and brand of Air Fryer) or until an instant-read thermometer registers 165ºF (74ºC) when inserted into the thickest part of the chicken, not touching the bone.
