This was the first time we travelled with our dog. He is £21. He does just fit in the carrier with it completely closed which is how it has to be to get on a plane. If your dog is unable to turn around in this, the Airlines may not let you on so be sure you know the size of your dog once on board we were able to open up the side pockets and give him more room to lay on the floor . Really love, the fact that it came on wheels in order to get him through the airport much quicker.
