Preheat the air fryer to 400°F (about 200°C) and let it run while you prepare the salmon.
Pat the salmon fillets dry with paper towels and arrange them skin-side down on a plate.
In a small bowl, whisk together the honey, olive oil, lemon juice, salt, black pepper, garlic powder, and dill until combined.
For frozen salmon: place the frozen fillets in the air fryer basket without overlapping and air fry for 6 minutes.
After 6 minutes, open the air fryer and brush the honey-lemon glaze over the top of each fillet, then close and air fry an additional 6 to 8 minutes, or until the internal temperature reaches 125–145°F depending on desired doneness.
For fresh salmon: place fillets in the air fryer, brush with glaze, and cook for 5 to 8 minutes depending on thickness, until cooked through.
Use tongs or a spatula to transfer the salmon to plates and serve immediately.
