they also have to have zippers in the top or side so the dog cannot escape.  I have flown my babies all over on almost every airline with the one from Walmart.  15.99.  Also it is not a good idea to take the hard on in the cabin.  You really will do much better with a soft sided one.  That can be squished in or down if need be.
