Trasporting Protein When Travelling

My job hasn't required a lot of plane travel lately (about four years actually). I know I used to always just put it in my checked luggage like you do, but I never had a problem with protein messes. I guess you could always have Alex to ship your proteins into smaller packages (I have him to ship mine in 2lb bags) and then include the unopened bag in your carry on luggage (yeah they may still open it then, but at least you have "eyes-on" to watch the mess-making ... perhaps you can get them to allow you to open it yourself for their inspection).

Just a thought ...
