Preheat: Preheat your air fryer to 400°F for 2 to 3 minutes.
Season the salmon: Pat the salmon dry with paper towels. Rub with olive oil, then season evenly with salt, pepper, and garlic powder.
Mix the glaze: In a small bowl, stir together soy sauce, lemon juice, and honey until smooth and pourable.
Air fry: Place salmon in the basket skin-side down (if using skin-on). Air fry at 400°F for 2 minutes, then flip and cook 2 minutes more.
Glaze and finish: Brush the honey lemon glaze over the salmon and air fry 1 more minute at 400°F, until the top looks glossy and the edges are lightly caramelized.
Rest and serve: Rest 1 minute, then serve. The salmon should flake easily and look opaque at the thickest point.
