The perfect carry-on packing list has two jobs: make sure you have every essential, and stop you from hauling things you'll never touch. Below is a practical, categorized checklist for an international trip — documents and money first, then tech, clothes, toiletries, health, and comfort. Work through each category, pack lean, and you can fly cabin-only even on longer trips.
1. Documents & money (the can't-replace list)
If you lose these, the trip stops — so pack them first and keep them on your body or in a bag that never leaves your side.
- Passport — valid well beyond your trip; many countries require at least 6 months' validity on arrival, so check the rules for your destination.
- Visa or entry authorization if your destination requires one (some countries use an online travel authorization for visa-free visitors) — confirm the current requirement for your passport.
- Boarding pass — on your phone and, ideally, a printed backup.
- Payment cards — a main card plus a backup on a different network, stored separately.
- Some local cash for taxis, tips and small vendors that don't take cards.
- Copies of your passport and cards, stored digitally and separately from the originals.
2. Tech (carry-on only for batteries)
Anything with a lithium battery — phones, laptops, and especially spare power banks — belongs in your carry-on, never a checked bag. Keep a dedicated pouch so nothing gets left in a seat pocket.
- Phone and its charger.
- Chargers and cables for every device, plus one spare cable.
- Universal travel adapter so your plugs fit the local outlets.
- Power bank for long transit days — it must travel in your carry-on. See choosing a travel power bank.
- Headphones and any e-reader or tablet you actually use.
3. Clothes & toiletries
Pack by weather and number of days, and lean on layers instead of bulky single-purpose items. Choose pieces that mix and match so a handful of items covers many outfits. Roll or use cubes to save space, and weigh the bag before you leave with a luggage scale if your airline has a weight limit.
- Tops and bottoms for the number of days, planning to re-wear and do a quick sink wash.
- Layers — a light insulating layer and a packable rain shell handle most climates.
- Underwear and socks, one comfortable pair of shoes plus something for evenings.
- Sleepwear and swimwear if relevant to your destination.
For toiletries in a carry-on, follow the 3-1-1 rule: liquids, gels and aerosols in containers of 3.4 oz (100 ml) or less, all fitting in one quart-size (1-liter) clear zip-top bag, one bag per traveler. Refillable travel toiletry bottles make this easy; see the TSA 3-1-1 rule explained for the details.
- Toothbrush, toothpaste, deodorant and travel-size shampoo/soap (or use hotel supplies).
- Skincare and sunscreen in 3.4 oz (100 ml) or smaller bottles.
- A quart-size clear bag to hold it all through security.
4. Health, comfort & misc
Medication rules are important: pack personal prescription medicine in its original labeled packaging, keep it in your carry-on, and bring enough for the whole trip plus a few spare days. Some countries restrict specific medicines, so check your destination's rules if you take anything unusual.
- Personal medications in original packaging, plus a small pain-reliever and any basics you rely on.
- Comfort kit — neck pillow, eye mask and earplugs make long flights far easier.
- Reusable water bottle (empty through security) and a few snacks.
- Miscellaneous — sunglasses, a small first-aid kit, a pen for landing cards, and a foldable tote for day trips.
