I literally only get Auntie Anne's at airports... mostly because I'm usually itching for a snack when I'm at an airport and the buttery smell of delicious carbo-loaded pretzels is usually filling the air.
This location of Auntie Anne's is located at the CLT Airport atrium, located right behind the piano player and The Body Shop. There was a slightly longer line when my colleague and I were there, but that might be because it was peak consultant time and we peoples get hungry!
Staff here were pretty average - not crazy friendly, but didn't give off a negative vibe. They were able to get the line down pretty quickly.
My go-to at Auntie Anne's is always the Sweet Almond.... it's the perfect sweet snack and doesn't require any dipping sauces. I love the crunchiness of the sweet almond topping. Note that you can also opt to get your pretzel without butter - it cuts down on both fat and calories.... but face it, if you're getting a pretzel for your snack, you might as well go big or go home.
Solid bread-y snack spot, along with Cinnabon a few stalls down.
