Stir together honey, soy sauce, and garlic powder until well combined, then split the mixture in half.
Place the salmon fillets in a dish and coat with half of the sauce. Refrigerate and let marinate for 30 minutes.
Heat your air fryer to 400°F.
Put the salmon into the air fryer basket and brush the remaining glaze over the fillets.
Cook the salmon in the air fryer for 7 to 8 minutes, adjusting the time based on thickness.
Serve immediately with the leftover sauce drizzled on top and garnish with sesame seeds and sliced green onions if desired.
