For some longer flights over meal time, I want to take a snack with me instead of relying on finding something int he terminal. AS a cheese lover, I would like to take some cheese with me. I have tried a couple of times cutting it up before hand and putting it in a bag, but by the time I got to it on the plane, it had become pretty disgusting. I am thinking that leaving it in one big piece and cutting it as I eat it would fix that issue.

One problem - the airport I am flying through now has very little in terms of concessions. I cant bring a knife with me through security, and I can't think of a way at my small airport where I can pilfer, er obtain, a plastic knife - either they only hand them out from the counter, or they are so cheap and flimsy that they cant cut through a piece of hard cheese.

So what other creative solutions are there? Any ideas?
