For the people that have travelled as couriers, I've a few questions:

- How are the goods you're transporting actually carried? Do you check it in as you'd normally do with your luggage, or does it get handled through the cargo dept?

- If it's checked as regular passenger baggage, when they ask if you packed your own bags, if they've been with you the whole time since packing, and if anyone unknown to you gave you something, how to you respond?

- At Customs at the destination country, how do you declare the goods? Presumably, much of the stuff is subject to duty. Are you given a list of items so you know what to declare?
