Meanwhile, brush both sides of the tortillas with oil and sprinkle with salt. Cut the tortillas into triangle, chip-sized pieces, making about 8 chips per tortilla. In batches, carefully add the sliced tortillas to the air fryer basket in a single layer.
Cook for 4 to 5 minutes. Near the end of cook time, open the air fryer and check in on the chips. Tip: If your air fryer is blowing the chips around, set a trivet (I use the one from my Instant Pot) gently on top of the chips. It will allow the air to circulate but keep them mostly in place. Remove any chips that might be close to overcooking before they burn and continue cooking any that need a little more time.

Notes
Avoid overlapping tortillas in the air fryer basket. It's important to keep them in a single layer. Cook in batches as necessary.
Weigh the pieces down to prevent them from blowing around in the basket. Lay a metal trivet (like the kind that comes with an electric pressure cooker) over the top of the unbaked tortilla pieces.
Be aware that flour tortilla chips have a cracker consistency and flavor. They're delicious and dippable, but not the same as restaurant-stye chips made with corn tortillas.
Flavor Variations
Spicy Lime Tortilla Chips: Before air frying, season with about 1/8 teaspoon of taco seasoning per tortilla. After cooking, drizzle with fresh lime juice.
Zesty Ranch Tortilla Chips: Season each chip with about 1/8 teaspoon of ranch seasoning before air frying.
Sweet Dessert Tortilla Chips: Before air frying, brush the tortillas with oil, about 1/2 teaspoon of maple syrup, and season with a pinch of cinnamon.
To Store Leftovers: Wait until the chips are completely cool, then transfer to an airtight container or bag. Store at room temperature and eat within 10 days.
