Here's what l do. l wrap the cheese in newspaper leave it in the fridge for a couple of nights pack it in my carryon when l get to the hotel l put it in the room fridge next morning back in the carryon for next flight to Khon Kaen then driven to Kalasin and straight in home fridge. Always about 6KG of cheese and always still cold each time. Never freeze it. Australia to Kalasin.
