Review on Comfortable & Convenient Pet Carrier For Medium Cats And Small Dogs - Washable Bed, Multiple Doors & Shoulder Strap - Easy In & Out - Escape Proof - Light Green by Pat Slater

Got this for my trip on Alaska Air which reportedly has stricter in cabin pet carriers than some airlines. A plethora of zippers allows easy access to this carrier -I bought the medium; size as advertised. My dog can't really stand in it but can lay down comfortably. This neatly collapses flat so plan to use my too big carrier and switch to this one if they reject it. Has an opening so it can slip over your luggage carrier and sit on top. The base is removable and has a stiff plastic insert inside a zippered case which adds structure and can be washed. Very high quality, will update if anything changes after my first trip. Will use in car with top open as a safety seat after my trip, buckled into my safety belt. There is a lightweight leash attachment inside compartment, not sure it would hold if your dog is aggressive.
