I would absolutely recommend the KB, we have the Alex bag, a big black one I think it's the biggest one they make, the one with 4 pouches on the sides, it's faux leather, looks soooo nice, very sturdy, we use it probably every day, so it gets lots of use. The handles and the base hold up well. the little side vents are really nice too. We have not flown anywhere yet but are looking to in the spring. And BTW Sprocket weights 10lbs and rats around in the bag quite a bit too

, it has a small leash w/hook inside to help teach your baby to stay inside but I found that catching their hair ONE time in the zipper, works even better

for staying down inside. When your thinking about the size of the bag remember to put a small blanket or Tshirt inside and maybe a chewie, they are calmer that way, of course I only have one dog in there too!! Just a thought. The bag is well worth the $$. I have forgotten do they come in white? Hmmmm maybe I
need another color

after all it's gonna be spring soon, right?????? No snow????
