We went to the ups store and shipped our luggage back home and took our fish home as part of of our luggage. We brought back three coolers of froze fish that weighted 50lbs each, and three fish boxes that also weighted 50lbs each. We flew from Anchorage to Los Vegas to Philly, Pa. to Raleigh, N.C. When we arrived our fish was nowhere to be found! We filed a lost claim with the airport. After spending over eight hours at the airport trying to locate the fish (with very little help from the airport) we left for home without the fish. I left my cell phone number with the airport and they called me about 40 miles up the road and said they had our fish at the airport. We turned around and got our fish. When we got home our fish had been in those containers for about 33 hours. The fish was not froze solid but was still froze enough till it was not hurt at all. Could not tell any difference in the cardboard fish boxes and the coolers.
