Packing for an international trip is two problems wearing one name. The first is what you will need, which is mostly a matter of climate and itinerary and is easy to overthink. The second is what the airline and the destination will let you carry, which is a set of rules, and rules are the part that costs money and time when you get them wrong.
The short version
- Some rules are actual rules. Lithium batteries above 160 watt hours are not allowed on a passenger aircraft at all, and spare batteries below that must travel in the cabin, never in a checked bag.
- Anything you cannot replace goes in the cabin: documents, medication, chargers, one change of clothes.
- Weight and size limits belong to the airline, and they differ per leg on a mixed itinerary.
- What is legal to carry is a question about the destination, not the airline. 30 of the 211 destinations the U.S. State Department covers address prescription medication in their local laws.
- Pack for the laundry, not for the itinerary. It is the single change that halves most bags.
What This Section Covers
These ten guides cover what to take, what to keep with you, what may not travel at all, and what to do when a bag does not arrive. They are written for U.S. travelers going abroad and for the group leaders who have to give twenty people one clear instruction.
What this section cannot give you is your airline’s allowance or your destination’s prohibited list. Those are published by the airline and by the country, they change, and they are the two things worth checking yourself before every trip.
The Decisions You Need to Make
Four decisions, and only the first two are really about clothes.
Carry-on only, or a checked bag?
It changes your connection times, your risk of arriving without your luggage, and how much you can buy while you are away. For a trip under about ten days with laundry available, carry-on only is realistic more often than people expect.
What has to be with me rather than under the aircraft?
Documents, medication, valuables, electronics, batteries and one change of clothes. This list is short and it is not negotiable, because a checked bag and its owner are not always in the same city.
What am I not allowed to bring?
Two different authorities answer this. The airline and aviation regulator decide what may fly; the destination decides what may enter. Batteries, drones, satellite equipment, some medication and anything resembling a weapon are the usual points of friction.
How many climates does this trip have?
An itinerary that crosses a mountain range, a desert and a coast is a layering problem, not a volume problem, and it is the one packing question worth genuinely planning.
Travel requirements, health guidance and safety conditions can change. Always confirm current requirements with the appropriate government or official authority before departure.

Plan Your Trip With LABUSA Travel
Most packing advice is generic because most trips are. An itinerary that crosses three climates, includes a light-aircraft transfer with a fifteen-kilogram limit, and ends with a formal dinner is not generic, and that is the kind of trip where the advice has to be specific.
