Place the chicken thighs in a bowl and drizzle with olive oil. Sprinkle the jerk seasoning and salt over the chicken, then rub everything evenly to coat each piece well.
Preheat the air fryer to 380 degrees F. Arrange the seasoned thighs in a single layer in the basket without overlapping.
Air fry the chicken for 18 to 22 minutes, flipping halfway through, until the internal temperature reaches 165 degrees F and the edges look crispy.
While the chicken cooks, combine the diced pineapple, red onion, cilantro, lime juice, and minced jalapeno in a separate bowl. Stir gently and set aside.
Remove the chicken from the air fryer and let it rest for 2 minutes. Spoon the pineapple salsa over each thigh before serving.
