[ TIPS · THE DISPATCH ]

The Carry-On Only Packing List That Actually Works

I checked bags for twenty years. Big ones. Heavy ones. One time a bag with a broken wheel I dragged through seven countries out of sheer stubbornness. Then I didn't. This is what changed.

I once checked a 32-kilogram bag to Barcelona for a long weekend. I’m not proud of this. The bag contained, among other things, three pairs of shoes I didn’t wear, a “just in case” cardigan for weather that was 30°C the entire trip, and a full-sized bottle of conditioner that the airline subsequently charged me forty euros for the privilege of transporting. The conditioner cost four euros.

The bag also took 45 minutes to arrive at baggage claim, during which time I stood watching the carousel with the specific blend of boredom and paranoid anxiety that is the signature emotion of checked luggage.

I have not checked a bag in four years. Here’s how.

The One Rule That Makes Everything Else Make Sense

One week, one bag. Two weeks, still one bag. Three weeks — you guessed it. The rule is not about duration; it’s about doing laundry. Once you accept that you will wash clothes at some point during a trip (which hotels, Airbnbs, laundromats, and even bathroom sinks make very easy), the mathematical case for packing for 14 days collapses. You need enough clothes for 5–7 days, maximum.

This is the mental unlock. Not the bag size, not the packing cubes — it’s accepting that laundry is part of the trip.

The Actual List

Clothes

ItemQuantityNotes
Trousers / pants2One casual, one that works for dinner
Tops / shirts4–5Mix of casual and smart
Underwear5–7Merino wool if you can; dries fast
Socks4–5 pairsMerino again; one pair of something thicker
Mid-layer (fleece or light jumper)1Doubles as plane blanket
Rain layer / packable jacket1Worth every gram
Shoes2One walking, one that isn’t a running shoe
Swimwear1 (if relevant)Doubles as gym wear in extremis
Nightwear1Lightweight, can also be lounge wear

This is it. If you’re cold-weather traveling, swap one of the tops for a thermal layer and downgrade the swimwear. You do not need more than this.

Toiletries

Decant into travel-size containers. Every single thing you use, ask: can I buy this at the destination if I run out? The answer is almost always yes. This means you take small amounts. Shampoo: 50ml. Conditioner: 50ml. Face wash: 30ml. Whatever moisturizer you use: decant it.

Toothbrush, toothpaste (travel size), deodorant, any prescription medication (always in carry-on, always), a basic first aid kit (plasters, painkillers, anti-diarrhea tablets, you’ll thank me), sunscreen decanted to 50ml.

The Tech Pile

Laptop or tablet (one, not both), phone, universal travel adapter, charging cables, portable battery. That’s it. The one thing most people forget: a small packing cube or pouch just for cables and chargers, so you’re not fishing around for your adapter at 6am.

The Three Enemies of Carry-On Only

“Just in case” items. These are the clothes-space killers. You will not need the fancy dress. You will not need the fourth pair of shoes. You will not need the travel umbrella when you already have a rain jacket.

Checking the weather obsessively and overpacking for it. Check the forecast. Pack for the most common condition. Bring the rain layer regardless. Do not pack a puffer coat and a medium jacket and a light fleece “just in case the layering changes.”

Not trusting yourself to figure things out. You can buy things abroad. You can use hotel shampoo in a crisis. You can wear the same trousers two days running; nobody is tracking this.

FAQ

What bag size should I use? For most airlines’ cabin bag allowance: 55x40x20cm is the standard international carry-on size (though budget European airlines like Ryanair allow only 40x20x25cm in overhead storage without a fee). Measure before you buy. Osprey Farpoint 40L, Away Carry-On, and Rimowa Cabin are all good options at different price points.

What about long trips — over three weeks? Same bag, same list, more laundry. I’ve done 5-week trips carry-on only. The only thing that changes is the frequency of washing and the willingness to buy a replacement sock in a pinch.

What if I need to look professional? One set of smart clothes that can be mixed and matched takes the space of two sets and covers twice as many occasions. A dark trouser and a shirt that isn’t a t-shirt will get you through almost any business dinner in the world. Shoes are the bottleneck: one pair of smarter shoes plus your walking shoes is the correct answer.
