I fly alot with my eggs, inter island and have also flown with them to California, Nebraska, Florida and and Missouri. I have never been denied boarding with them, but I also do not disclose to the airlines itself what I am carrying when I check in for my flight, I try to keep the less attention on me as possible. TSA doesnt bother asking any questions, I think they assume that the airlines have approved them. I do not send them through the x rays though, I have them hand checked. I also dont have to worry about refigeration while transporting the eggs because I dont refigerate them to begin with. They always arrive to their destination unharmed, and I do not take any extra steps in wrapping them. I also travel the airlines alot inter island with puppies and baby chickens, I dont bring attention to the carriers and nobody asks, so I dont tell. Works like a charm for me.
