Carry-On Packing Checklist: How to Travel With Just One Bag
No checked-bag fees, no waiting at the carousel, no lost luggage. Here's exactly what fits — and what to leave at home.
A good carry-on packing checklist keeps you to the essentials: a small capsule wardrobe in colours that mix and match, one pair of extra shoes at most, a clear bag of travel-size liquids, your documents and chargers, and a few comfort items for the journey. With smart packing, one cabin bag can comfortably cover a week or more.
I switched to carry-on only travel after an airline lost my suitcase on the way to a wedding. I’ve never looked back. It’s faster, cheaper and far less stressful — and it forces you to pack only what you’ll actually use.
First, check your airline’s size rules
Carry-on limits vary by airline and fare type. Many major US airlines allow a bag of around 22 × 14 × 9 inches (56 × 36 × 23 cm) plus a smaller personal item that fits under the seat. Budget airlines and basic economy fares may allow only the personal item. Check your booking before you pack, and weigh your bag if the airline has a weight limit.
The complete carry-on packing checklist
Clothes (for about 7 days)
- 3–4 tops that all go with your bottoms
- 2 pairs of trousers, jeans or skirts (wear the bulkiest on the plane)

- 1 jacket, worn on the plane
- 5–7 pairs of underwear and socks (or fewer, and plan to wash)
- 1 set of sleepwear
- 1 outfit for exercise or swimming if needed
- 1 smarter outfit if you have an event
Shoes
- Wear your heaviest pair on the plane.
- Pack one lighter pair, such as trainers or sandals.
- Stuff socks inside shoes to save space.
Toiletries
- Toothbrush and travel-size toothpaste
- Deodorant (solid saves liquid space)
- Shampoo and conditioner, or solid bars

Liquids: the TSA 3-1-1 rule
In the US, liquids in carry-on bags follow the TSA’s 3-1-1 rule: containers of 3.4 ounces (100 ml) or less, all fitting in one clear, quart-sized bag, one bag per passenger. Many other countries use similar 100 ml limits, although some airports with newer scanners are relaxing the rules. Always check the latest guidance on the TSA website or your departure airport’s site.
| Item | Carry-on? | Notes |
|---|---|---|
| Liquids under 100 ml | Yes | In one clear quart bag |
| Solid toiletries | Yes | No limit in most places |
| Power banks | Yes (only carry-on) | Not allowed in checked bags |
| Prescription medication | Yes | Keep in original packaging |
| Baby formula and breast milk | Yes | Larger amounts allowed; declare at security |
How to pack a carry-on so everything fits
- Lay everything out first. Then remove a third of it.
- Roll soft items like T-shirts and sleepwear; fold structured items like shirts and blazers.
- Use packing cubes to compress clothes and keep things organised.
- Put heavy items at the wheel end of a rolling bag so it stands upright.
- Fill every gap — shoes, corners and pockets are storage space.
- Keep liquids and electronics on top for quick security checks.
The colour trick: choose clothes in two or three neutral colours plus one accent. Everything matches everything else, so five pieces create a week of outfits.
What not to pack
- “Just in case” outfits you’ve never worn at home.
- Full-size toiletries — decant or buy there.
- More than two pairs of shoes.
- Heavy books when an e-reader will do.
- Anything you’d be devastated to lose.
Plan to do laundry
For trips longer than a week, pack for five to seven days and wash clothes as you go. Most hotels and rentals have laundry facilities, and a small travel-size detergent sheet takes up almost no space. Quick-dry fabrics make sink washing easy.
Travelling light also makes it easier to grab budget fares — our guide on how to find cheap flights explains why bag fees matter so much. Driving instead? See our tips for planning a road trip on a budget.
