I think Airborne is the worst of all your choices. If you ask 5 different people, you will get 5 different answers. I have not had any problems with UPS or FED EX, but Airborne lost a snake last month that was being shipped to me. The box had been retaped, but when I opened it, there was 4 containers and 3 snakes.(one of the 3 remaining snakes died the next day.) There was obviously a live snake in the container recently, because there was fresh feces still in the container. If the buyer is willing to pay, Delta Dash is the best way to go, since the animals will be shipped and received in less than 6 hours in most cases. But, remember, anything can go wrong, and sometimes it does. All the shipping companies are jerks when it comes to shipping snakes, so sometimes you have to conceal the identity and ship them listed as lizards. You can get permits from different shipping companies, but that is a tedious process, and you still have no guarantee that your animals won't sit in a hot depot overnight(or over a weekend) when a mistake is made, and believe me, sooner or later, a mistake will be made. Just hope it happens with a $30 gecko and not a Piebald Ball Python. Good luck with the shipping!!!
