ok, the short version is that one of my gf's aunts wants to make something, freeze it and send it back with her on the plane. She told my gf that she had done this herself before and that they put it in a freezer on the plane for her for?? I have never heard of this before and it would really surprise me. The flight is long enough that it would not just be frozen still and it is not a direct flight. About 9hrs and two planes total.

Is it possible the check something in a cardboard box frozen and still have it frozen 10hrs later? Odd question huh lol

thanks
