If I'm not mistaken, it is only illegal to ship snakes through USPS. It is against company policy to ship snakes through FedEX and UPS, although, they allow some breeders to use their services without question. FedEX does allow breeders to become varified shippers by going through a shipping test. I've made several hundred shipments with UPS over the years....and believe it or not, with excellent results. In my opinion, shipping via airlines is just as stressful on the animals as with UPS or FedEX. I've had some expensive animals shipped to me through Delta, only for the airlines to "misplace" the animals for many hours, and when they finally arrived a friend of the service rep was beating and shaking the container.
When shipping high end or expensive animals, the only sure way is to deliver them in person. However, there will eventually be mistakes when using any method of shipment.
