Just flew SW last week with two pups...we went to pick up the dog we were adopting.
Bama is 6 lbs. she has a Sherpa medium because it was on sale. I had no idea it didn't meet SW requirements when I got it, but because the top can squish down and she still has room it's not an issue. When I had to get a carrier for Bear, who is 12.5, I realized the small Sherpa was too small for him, and the medium was too big for SW.
So I went to SW's website and bought their official carrier. I think it goes up to 25 lbs. it costs around $50 I think.
It doesn't feel as firm and sturdy as the Sherpa, but it is adequately enough. And because its the airline's official carrier as long as your pet fits they can't give you any hassle.
