Wholesalers are packing shipments throughout the day. The chances that they have been sitting for hours inside a bag are about the same as an e-tailers. Of course if you do have your shipments sent from a wholesaler, you commonly do get it shipped via airport to airport, but you can also request this service from most of the e-tailers out there as well. The main problem with e-tail, is the convenience factor, in that people DO NOT want to go to the airport to pick up the orders that they have placed. Most customers want the door to door service that FedEx, UPS and DHL provides. My opinion on this has always been to offer airport to airport shipping as an option, and we spell out the various advantages of this as well. Back when I was with FFE, we had a lot of customers from Las Vegas placing orders, and sometimes their orders would come in DOA. Well we asked a few questions, and found that Vegas shipments with FedEx were being trucked, not flown. This resulted in a lot of frozen fish during the winter time, so we suggested South West shipping, and never had a complaint afterwards. All you have to do is ask the company in question, if they offer this service, and if they do, I highly suggest that you take full advantage. It may cost a little more, but I can guarantee that you will have a far higher success rate, as well as healthier animals, even in winter shipping conditions.
