Wash the russet potatoes and pat dry with a paper towel.
Using a fork, poke holes in the potato all over. Rub olive oil, salt, and pepper on all sides of the potato. Place into the air fryer at 400F for 1 hour and 10 minutes. When done, the outside will be crisp and the inside should be fork tender.
Carefully cut the potato in half and scoop out the inside into a bowl. Add butter, salt, pepper, and heavy whipping cream to the bowl with the potatoes. Use a hand mixer to whip the potatoes until light and fluffy. Add more butter and heavy cream if needed. Some potatoes need a bit more fat than others when whipping.
Add the whipped potato back into the potato skin using a spoon or a pastry bag with a large tip. The whipped mixture will fill 4-5 half skins. Air fry for 4 minutes on 400F just to brown the top.
Remove from air fryer and top with cheese, chives, and bacon. Optionally, you can return the potatoes to the air fryer for 2 minutes to melt the cheese.
