Hello!!
I have the Alex Gunmetal and I LOVE it so much!!!
I actually have not tried to sneak my dog in anywhere but have used it many times now when I go to the mall that allows dogs, when we are outside Snick walks, and when we are in stores, he's in the bag happy as pie with his lil head sticking out looking at everything.
They are superb quality bags and yes, airline approved on most airlines.
Snick knows it's his bag so when it comes out of the closet, he gets very exicted knowing we are going out. Too cute!
RDB911 is a seller here on YT that carries KB Bags. Incredible seller, best prices, and lightning fast shipping.
Smiles-
