There was a moment of panic after the birds were picked up but it all worked out ok. I filled out live animal stickers for the carriers and Delta Cargo put them on the wrong carriers. I made sure to write the airway bill number on the carrier itself as well as on an envelope that I taped to the back. They each got the right bird but the cargo stickers had the wrong names on them. They are both girls and siblings so they look the same, but trying to sort that out after one of them drove 8 hours to pick the bird up would have been a nightmare.
