Preheat your air fryer per manufacturer's recommendation.
Spray the wings with duck fat. Just a few squirts will do. I like to put the wings into a bowl, give them a quick spray, turn then, and give them another quick spray.
Sprinkle the wings with seasoning. Turn, and add a bit more seasoning. Alternatively, place the wings into a bag or resealable container and sprinkle with the seasoning. Close the container and toss gently to coat.
Add the wings to the basket (be careful it's hot!). If you have trouble fitting them without overlapping, stand the drumettes along the sides of the basket.
Cook at 360 F for 12 minutes for large wings, 10 minutes for smaller ones.
Carefully flip the wings (rotate the drumettes if they are standing) and cook another 12 minutes again (10 minutes for smaller wings) at 375 F.
Flip the wings one last time. Increase the temperature to 390 F and cook another 6 minutes (4 minutes for smaller wings).
Remove and toss with your favorite wing sauce or sprinkle with more seasoning.
