Preheat the air fryer to 400° F. In a small bowl, stir together the honey, ginger, and garlic, then brush it on both sides of the salmon. Drizzle the asparagus with the oil and season with salt and pepper.
Line the air fryer basket with a piece of parchment paper, add the asparagus in an even layer, and place the salmon on top. Cook for 10 minutes.
Serve with the remaining honey mixture on top of the salmon alongside the asparagus.
