Review on 🐾 MASKEYON TSA Airline Approved Soft Sided Pet Carrier | Top Loading, Expandable 4-Side Large Travel Cats Carrier | Collapsible with 3 Removable Washable Pads and 3 Pockets | Suitable for Cats, Kittens, and Small Dogs by Jennifer Duncan

My puppy was very comfortable in this carrier. I didn't stop long enough to let her try the side porch. She was very happy, just sitting there tied to a stretcher. Once I received the terminal I unzipped it and she sat down and enjoyed the ride, was able to look around and interact. As for placing under the seat...when I flew in 2021 the seats were so full that the flight crew didn't even ask me to put it under the seat, which is good because that would never happen. fit. This is exactly the size Delta requires for traveling with a pet. At the time of the flight, my dog weighed 7 pounds.
