I've been to the Kenai twice. Both times the wax boxes were used. The guide took good care of the fish, vacume packed with industrial packer and deep frooze. Airport time from Kenai to Anchorge to Seattle then 2 to 3 hours to get home, the fish was partially thawed both times. If the guide doesn't supply dry ice tell him you want it and purchase it yourself. He should know were to get it. Wrap it in newspaper yourself that will take you about 5 minutes. These extras will save you alot of stress worring about your expensive fish thawing on you before you get it home to your freezer.
