Did the bag from Karlie 38187 Carrying Case English Style 50 x 30 x 22 chosen for its low weight. I needed them to a puppy on the plane to transport in the cabin. Since the puppy was estimated at about 7 1/2 kg, I had not much choice. Since this carrying case out of the question. Eventually, the puppy had 8.2 kg. The bag held this weight from super. The dog could lie down and curl up. He seemed even comfortable. For short flights and transports, where you can open the top cover again and again, this bag is highly recommended. In spite of some serious weight of my puppy, I had with this bag at the airport no problems and was allowed to take the dog into the cabin. The workmanship is good and the price - performance ratio tip. Can therefore only recommend this bag.
