Thanks! Has anyone carried on a Large Sherpa? The pup will be 4 months when I take her and I'm worried about whether she'll fit in a Medium carrier. Medium carriers are guaranteed accepted on American, though I'm guessing they might take a large if she'd still under the weight restriction (20 lbs) and there's room?
Thanks everyone! Definitely will pick up a Sherpa carrier. She's riding with me in the cabin. Was supposed to receive her by cargo but felt the pup would be very distressed after such a long trip. I worry a little about going through security, since she won't know me very well yet.
