This is the reason that I bought this particular bag. I have a 16 lb Bichon who needed to travel in cabin with me. I looked everywhere to find a bag that would work with most airlines. Even though there was an "AA" approved bag, I chose this one instead because it came in a better size for my pup. We flew on both American Eagle prop plane(where you need to ask for the non-single seat) and on a regular AA plane. The bag was a tight fit on Eagle and stuck out a bit into the area for my feet, but since I had no seat mate, it wasn't a big deal. It would have been something 'doable' if I had to (since AEagle flights are short). I had to turn the bag sideways and scoot it into position under the seat in front of me. However, it was a perfect fit under on the other planes that we took. Plenty of room for my pup to turn around and get comfy. The inner lining was great because it is removable for ease of cleaning, but nice and soft for the comfort of my dog. All the additional items (folding water dish, bag of food, leash and harness) fit into the end pocket without difficulty and didn't cut into the space for my dog. Using this bag (as opposed to the carrier that someone else had on the plane) was a great plus because of the AA Approved status and the Guaranteed On Board Certificate (offered through the Sherpa web site). The agent looked over the paperwork and didn't make me 'size it' like the others had to do. (Less trauma for the pup). The bag maintained its construction and didn't seem to buckle (like some other bags I have tried) even when I threw it over my shoulder to carry him through the airport. (OK, I didn't throw it, I gently placed it on my shoulder.) In fact, the bag is such a hit with my pup that he has been sleeping in it at night as we travel and doesn't mind being closed in it when we have visitors who are afraid of dogs. Overall, I am very pleased not only with the bag and its construction, but also the ease of use when flying. If this is what you are looking for, it is a perfect way to take your loved pet along.
