Carry-On Packing List: What to Bring in Your Hand Luggage

There is a particular kind of freedom in walking straight past the baggage carousel and out of the airport, with no waiting, no oversize fees and no quiet worry that your bag boarded a different flight than you did. Packing for a trip in hand luggage alone is a skill worth learning, and once it clicks most people never go back. This carry-on packing list is written for Irish travellers who want to move light, whether that is a long weekend in Lisbon, a week of island hopping, or a work trip where every minute saved at the far end matters.

The aim is not to go without. It is to edit. A good carry-on setup holds everything you actually use and nothing you packed out of habit, and it sits inside the cabin bag limits that airlines such as Ryanair and Aer Lingus enforce to the centimetre. Get the bag right, pack with a little method, and you can be away for a week with a single bag on your back and your hands free.

Start with the right cabin bag

Everything starts with the bag, because its size decides your limit before you pack a single thing. A proper cabin bag is built to sit within airline dimensions, opens flat like a small case rather than a deep top loader so you can see everything at once, and carries its weight close to your back. The CabinZero Classic 28L shown above is a fine example of the type: light, generously sized for the cabin, hard wearing, and simple enough to live out of for several days at a time.

If you want a pack designed to the carry-on brief from the ground up, the Osprey Daylite Carry-On Travel Pack 44 is sized to airline standards and loads from the front like a suitcase. If you would rather a soft duffel that yields to the shape of an overhead locker, the smaller The North Face Base Camp Duffel in its 31 litre size is tough, weather resistant and easy to carry. It is worth browsing the full range of cabin bags and travel luggage to compare shapes and capacities before you commit, because the best bag for a minimalist city break is not always the right one for a trip with bulkier kit.

Know your airline's cabin bag rules

Irish carriers are strict, and the rules differ by airline and by fare, so it pays to know exactly what you are entitled to before you start packing. Most airlines now split the cabin allowance in two. There is a small personal bag that must fit under the seat in front of you, usually included with the basic fare, and a larger cabin bag for the overhead locker that tends to cost extra or comes bundled with priority boarding. Ryanair and Aer Lingus both publish their current maximum dimensions on their own websites, and they really do measure at the gate. Check the allowance attached to the fare you actually booked rather than the airline in general, then measure your bag once it is fully packed, including wheels and handles. A bag that slips into the size frame when empty can fail it when stuffed, and that is an expensive lesson to learn at the boarding gate.

Clothes: pack layers, not outfits

The single biggest space saving comes from packing a small set of layers that mix and match, rather than a separate outfit for every day. Pick a colour palette where most things work together, lean on merino or technical fabrics that resist odour and dry overnight, and plan to rinse a few items mid-trip rather than carrying a clean shirt for each morning. A packable waterproof and a light insulated layer will cover most of what a summer abroad throws at you, and both crush down to almost nothing in the bag. Packing cubes are the quiet hero of this section. They compress soft clothing, keep everything sorted by type, and turn the daily hunt for a clean t-shirt into a five second job.

Liquids, wash kit and the 100ml rule

Airport security still limits liquids in hand luggage to containers of 100ml or less, carried together in a single clear resealable bag. Some airports are rolling out newer scanners that may eventually relax this, but the change is not universal, so it is safer to pack for the strict version every time. Decant your essentials into small refillable bottles, or sidestep the rule altogether with solid alternatives such as bar shampoo, a solid moisturiser or sun cream, and toothpaste tabs. A compact wash bag that folds flat or hangs from a hook keeps everything in one place and off the hotel sink, and a small microfibre travel towel takes up a fraction of the space of anything you would use at home.

Tech, documents and what stays close

A few things should always travel in the cabin rather than the hold, and as a carry-on traveller you have no hold bag to lose, which removes a whole category of worry. Power banks and spare batteries must be carried in hand luggage and are not allowed in checked bags, so keep yours easy to reach. Bring a single travel adaptor, only the charging cables you actually need, your headphones, and an offline or paper copy of your boarding pass and bookings in case a phone dies at the wrong moment. Keep passport, cards, keys and any medication in one consistent pocket so you are never emptying the whole bag to find them in a security queue.

Packing technique: roll, cube and balance the load

How you pack matters almost as much as what you pack. Roll soft garments rather than folding them to save space and limit creasing, and slot the rolls into packing cubes so the bag holds its shape. Pack heavier items low and close to your back so the load sits comfortably and does not drag on your shoulders. Fill the dead space inside shoes with socks, chargers or sunglasses, and keep anything you will want in flight, such as a layer, headphones and your liquids bag, near the top or in an outer pocket. A well packed carry-on is not just smaller, it is faster and calmer to live out of all week.

Before you head to the airport

A couple of small habits separate a smooth departure from a stressful one. Weigh your packed bag at home on a luggage or bathroom scale, because cabin bags have weight limits as well as size limits and the gate is the wrong place to find that out. Check the latest security and customs restrictions for your destination, as rules on items like certain foods, sports gear and batteries vary from country to country. And if you are picking up a new bag or any last pieces of kit before you travel, you can order online and collect in one of our stores, which is handy when you are flying at short notice.

If you are packing for a festival rather than a flight, our festival camping checklist covers the very different kit that kind of trip needs.

Travelling with carry-on only is mostly a question of confidence. The first time, you will feel sure you have forgotten something. By the third trip, you will wonder why you ever stood at a baggage belt. Start with a bag that fits the cabin, pack a tight set of layers you can wash and rewear, respect the liquids rule, and keep the irreplaceable things close. Do that, and your hand luggage will carry everything a week away actually needs.
