# Packing list Carry-on checklist for a week of trips with one bag and a laptop. - One shirt per two days, always folded not rolled. - Spare battery in the personal item, never the checked bag. - Toiletries under the hundred millilitre rule in one clear pouch. - A single pair of shoes that survives both rain and a dinner. The laptop bag holds the cables, the drive and the paper documents, and it is the thing that gets opened at every security checkpoint, so it stays boring and easy to repack.
