Snakes are air-shipped all the time pretty safely, especially when the dead of winter is avoided. They must be properly packed though, in a thick styro-foam container with a special heat pack & crumpled paper for padding around the snake bag, in which the snake has been secured. Best to get professional help though. Um, for the packing, not for having a pet snake.![]()

I've only moved cross country with my snakes by car, & I packed them in much the same way. The styro-foam box protects from both excess heat or cold, & snakes just relax & sleep while traveling. Air shipping is COLD though (in the cargo hold of a plane, so they need careful use of heat pack). DON'T feed your snake for at least 10-14 days prior to shipment, so they don't end up taking a dump in the bag & be stuck in it for the whole trip.
