I remember many weeks back reading about the very same topic. I really feel for you, not wanting to fly out such a tiny baby. Here is the name of a ground pet transportaion company. "Pro-Pet Transports" - This is a quote from their site:
"Moving pets safely and comfortably to their destination is our only business.
Our nation wide attended ground pet transportation service eliminates the trauma and inconvenience of moving pets by other methods and provides for the best possible care during the journey. We also offer carrier cushions, animal toys and other quality transportation accessories you may purchase to make your pet's journey more comfortable."

Good luck to you, your new baby is just adorable! Being a totaly Chocoholic, I love the name Snickers. Don't you find that any Yorkie, anyway, you just want to eat right up??
