Flew with my cat last week and this fit under the seat without a fight. The way it collapses down to 3 inches makes stashing it in the hotel closet so easy.

The 360-degree zipper is the best part—I can open the whole top and my cat just walks in instead of me shoving her through a little door. Flew with it last week and the flight attendants didn't even blink at it.

Folded it down to about 3 inches and it slid right under the seat in front of me with room to spare. The 360 zipper made it easy to reach in and pet my dog mid-flight without unzipping the whole top.
