Packing only a carry on bag can feel impossible the first time you try it. Yet many travellers find that once they do it, they never want to go back. You skip the baggage queue, you can move between trains and hotels easily and you never worry about a lost suitcase.

The secret is not squeezing more in. It is packing less, and packing smarter. Here is a simple system that works for a week away in most climates.

Check the rules first

Cabin bag allowances differ between airlines and sometimes between fare types on the same airline. Before you pack, check:

  • The maximum size of a cabin bag.
  • Whether there is a weight limit.
  • Whether your fare includes a full size cabin bag or only a small personal item.
  • The rules for liquids in your hand luggage at the airports you will pass through.

Check this on your airline's official website close to your trip, because allowances can change.

Choose the right bag

A good carry on bag is light, sturdy and easy to carry. Some people prefer a small wheeled case, others a travel backpack. Wheeled bags are easy on smooth floors, while backpacks are better on stairs, cobbled streets and crowded transport. Choose the one that suits the way you travel.

Packing cubes or simple pouches help a lot. They keep things organised and make it easy to find what you need without unpacking everything.

Build a small capsule wardrobe

The biggest space saver is choosing clothes that all work together. Pick two or three main colours that match, and make sure every top goes with every bottom. That way, a few items create many outfits.

A starting list for a week might include:

  • Tops: four or five, mixing short and long sleeves depending on the weather.
  • Bottoms: two or three, such as trousers, jeans or a skirt.
  • Layer: one warm layer, such as a jumper or fleece.
  • Outer layer: one light jacket, ideally water resistant.
  • Underwear and socks: enough for four or five days.
  • Sleepwear: one set.
  • Shoes: one comfortable pair to wear and, if needed, one light extra pair.

Adjust this list for your destination and plans. A beach trip needs swimwear. A city break in winter needs warmer layers.

Plan a quick wash

Rather than packing a fresh outfit for every day, plan to wash a few items midway through your trip. Many accommodations have laundry facilities, or you can hand wash small items in a sink with a little travel detergent. Quick drying fabrics make this much easier.

This one habit can cut the amount of clothing you need almost in half.

Wear your bulkiest items

On travel days, wear your heaviest shoes, your warmest layer and your jacket. They take up a lot of space in a bag and are easy to carry on your body. You can take off a layer once you are on board.

Keep toiletries small

Toiletries can take up a surprising amount of space. To keep them compact:

  • Use small refillable containers for liquids.
  • Consider solid versions of products such as shampoo or soap where they suit you.
  • Pack only what you will use in a week.
  • Check whether your accommodation provides basics such as shampoo or a hairdryer.

Keep liquids together in one clear bag so you can take them out quickly at security if required.

Roll, fold or both

People debate rolling versus folding, but both work. Rolling soft items like t shirts can reduce creases and fit neatly into cubes. Folding works well for structured items such as shirts. Try both and see what suits your clothes and bag.

Fill empty spaces with small items. Socks fit inside shoes, and chargers fit into gaps along the edges of your bag.

Pack a small personal item

If your fare allows a personal item, use it for things you want within reach during the journey:

  • Passport and travel documents.
  • Phone, charger and a power bank.
  • Medication.
  • A light snack and an empty water bottle.
  • Headphones and something to read.

Keep valuables and essentials with you rather than in a bag that might need to go in the hold if the cabin is full.

Do a test pack

A few days before you leave, pack your bag completely. Then lift it, walk around with it and see if it closes easily. If it feels heavy or overstuffed, take something out. A useful question is: would I buy this again if I needed it there? If the answer is yes and it is easy to find, you may not need to bring it.

Leave a little room

Try to leave a small amount of space for anything you pick up during the trip. A foldable tote bag weighs almost nothing and can help on the way home.

Lighter bag, lighter trip

Packing a carry on for a week is a skill, and it gets easier each time. Start with the airline's rules, choose clothes that mix and match, plan a quick wash and wear your bulkiest items. You will spend less time managing your luggage and more time enjoying where you are.
