Soft, Airy, Breadsticks

What makes some breadsticks/rolls softer and airier than others? I want to make them, but don’t know how to achieve THAT result. I have had them in 2 places in particular, that were to die for…along with dipping them in a Alfredo sauce vs a Marinara. They practically “limp” when you pick them up. Beba’s Italian Rest’r. in Lawrenceville, Ga is one of them. They have “Beba’s Garlic Rolls”, and the other is Breadsticks from John’s Pizzaria in Munster, Indiana. How do they do that?
