I got a Samonite from a local pet store. Go to JetBlue's website and see if they have any specific regulations. Otherwise most pet stores carry a few crates that are marked as airline approved. Do do a search for pet travel. There are several out there. Some tips, get there early. You dog will have to come out of the crate for security. Take potty breaks before you got in and after you land. You may want to give the dog a chew toy for take off, so help pop thier ears. The dog will have to go under the seat for take off and land, but if I have a space beside me I take my crate and put it beside me. One thing, my dog was very scared during the flight. Actually growled at a flight attendent, something he has NEVER done before. So just a warning. Good luck and happy trails.
