Review on 🐾 FOYOPET Pet Carrier Backpack for Cats and Dogs Up to 22 lbs | Collapsible Cat Carrier for Large Cats | Small Dog Carrier with Ventilated Design for Puppies, Rabbits, and Small Pets Travel, Hiking & Outdoor Use by Tiffany Santos

I have never taken my dog on a flight because I didn't want him to be crushed in a seat without full ventilation. This fully ventilated pack solves that problem, and while technically it was a bit oversized, the baffle made it flexible to fit under the seat for takeoff and landing. The Allegiant flight was less than 2 hours and luckily I had a seat next to me otherwise it would have been awkward for both of us to be in the same leg section. Boarding the plane itself was cramped and I'm tall so it was nice to have a neighbor offer to transfer. I put it upright after take off but the flight attendant asked for an under seat bag in my lap on my return but the short flight made it ok and my dog had enough space to sleep comfortably.
