Sorry I didn't see your post before. I've been kind of out of it here....
I pm'd you.
As for airplane travel... I've never done that with any of mine so I don't know first hand.
I know that there is dehydrated food that could easily be taken along - it's not raw, but it would be fine for the plane trip. I'll see if I can come up with anything else.. my brain isn't working at full speed yet.
