What should be on a carry-on one-bag packing checklist?
A carry-on one-bag checklist should cover eight groups: a main bag sized to your airline’s cabin rules plus a personal item, a capsule wardrobe for about one week plus laundry, one or two pairs of shoes, security-aware toiletries and meds, documents and money, tech with the power bank in the cabin, an access layer for the flight, and day-of-travel checks.

Free for personal use. The PDF is one page of tick boxes; this page prints cleanly from any browser too.

Bag & setup

- Personal item that fits under the seat (daypack, sling, or laptop bag)
- 2–4 packing cubes or folders by category (tops / bottoms / underwear & sleep)
- Small pouch for cables and adapters
- A little empty space left so the bag still squeezes into a sizer
Clothing (about one week + laundry)
- 5–7 tops that mix and match
- 2–3 bottoms
- 1 warm layer (light sweater or fleece)
- 1 packable rain shell or wind jacket
- Underwear and socks for 5–8 days
- Sleepwear
- Optional: one nicer outfit for dinners or events
- Optional: swimwear, scarf, or beanie for climate
Shoes
- Main walking shoes — wear them on travel days
- Optional second pair (light sandals, flats, or dressable sneakers)
Toiletries & health
- Clear liquids bag where your departure airport requires it
- Solid or mini toiletries: toothbrush, toothpaste, deodorant

Day of travel

- Re-check airline size, weight, and personal-item rules for this fare
Notes: ______________________________________________
How to use this checklist
Lay everything out first, tick items as they go into the bag, and cut anything that only appears as a “just in case.” The clothing counts follow the capsule approach in the carry-on one-bag packing guide; the split between bags follows personal item vs carry-on. For a longer worked example, see the Europe 14-day list.
General packing guidance only — not medical, legal, or airline-policy advice. Liquids, battery, and cabin bag rules vary by airport and carrier.
