Preheat the air fryer to 375°F. Line the air fryer basket with parchment.
Cut each slice of bread into 4 sticks.
Whisk together the eggs, milk, cinnamon, sugar and salt together in a shallow bowl.
Dip each stick into the egg mixture, rolling to coat, and place in the air fryer basket. Repeat with as many pieces as will fit in the air fryer at once.
Air fry for 6-8 minutes, flipping halfway through, until sticks are golden and puffed.
