Preheat oven to 400 degrees. For an easy clean up, line a baking tray with some aluminum foil. Place a baking rack on top of the baking tray and grease that with some cooking spray.
If you have whole chicken wings, cut at the joints to remove the wing tip and divide into the flats and drumettes.
Season the chicken with salt (and pepper, if desired), then sprinkle on a light coating of cornstarch, just enough for a very light dusting.
Place the chicken on the baking rack, skin side up, and spray with a little bit of cooking spray. Bake in the oven for about 30 minutes. I do not flip my chicken over. Honestly, the bottom side of the chicken wing, without all the skin, doesn't really get crispy anyways. Therefore, I just like to let the skin side get as crispy as possible. The bottom side will still be nice and a bit crispy, since we are using the rack; however, I just like to focus on the top side.
When time is starting to run out on the oven, make sure to start preheating your air fryer to 400 degrees. Having a preheated air fryer is very important to continue cooking the chicken wings. I will also grease the air fryer with cooking spray, to make sure nothing sticks.
When the 30 minutes are up and the air fryer is preheated, transfer the chicken to the air fryer, skin side up again. Spray with a little more cooking spray and air fry for another 5 minutes, until the chicken is fully cooked.
You can skip the air fryer and leave the chicken in the oven for about 35-40 minutes total, until fully cooked.
