If you are interested in a very well made carrier that is airline approved, I can recommend a Petflys. In fact, I could recommend a very nice, aboslutely new Roundup Petflys carrier. It looks like this:
http://petflys.com/buckaroo.html and comes with both a short and shoulder strap and the cute little leopard print blanket. For sale at about 1/2 the price of new! I have several carriers and have decided to stick with a large one that both of my Yorkies can fit well -- so I am going to sell the others.
