I can't really remember and I'm sure it's all changed post 9/11 anyway, so what are the rules? Are there some things that can only go in checked or hand baggage?
We're going on a trekking holiday that will take in some remote locations and the advice from previous participants is to take lots of snacks for DC. Can these go in the hold luggage or will temperatures be too extreme? Am thinking biscuits, chocolate, nuts and dried fruit (unless anyone has better ideas!)
