Here is a link to the bag I use for flying with Scooter.
Bergan Comfort Carrier - Carriers - Dog - PetSmart
I searched all over trying to find the right bag. This is bag #3 and it is by far my favorite. We have travelled quite a bit and the bag is still holding its own. The only thingI have had an issue with is the bed/pad. After one flight, it bunched up and looked uncomfortable. It is made to be removed and washed so I got creative and put my own pad in the bottom. Now, Scooter really likes the bag.
I could care less about being original, I just wanted a good sturdy bag that allowed Scooter to travel in style. I would buy it again but mine is in such good shape that I dont even need to think about it now.
Good luck in your search.
