I think if it's a soft-sided one -- and it can be smooshed under the seat, you should be fine. They have never measured my carrier. The only other problem I have come across, is depending on the plane, the carrier won't fit under one of the seats (usually the aisle, but sometimes the window). It's too narrow. But, since you're traveling with your BF, you'll probably have seats together, and one of them will fit. Just my experience... |
