Cooking chicken breast in an air fryer means cooking with less oil. In my nutrition course, I learnt that healthy fats are good for you, in moderation. That's why I love to use avocado oil in cooking. It also has a high smoke point. Air frying foods means using even less oil. So, yes, air fried food is good for you. This is especially the case with fried chicken, where you can get amazingly crispy results with just a fraction of the oil!
