What is the access-order principle for carry-on packing?

The access-order principle means packing items in reverse order of when you need them. Items you need first (toiletries at security, laptop) go last into the bag so they are on top or most accessible. Items you won't need until your destination go in first.

Where should toiletries go in a carry-on bag?

Pack your clear toiletries bag in the most accessible outer pocket or at the very top of the main compartment. You need to pull it out immediately at the security checkpoint, so it should never be buried under clothing or electronics.

Do packing cubes actually help in a carry-on?

Yes, significantly. Packing cubes compress soft clothing, keep items from shifting in transit, and let you find things without unpacking everything. In a 40-litre carry-on, two medium cubes (clothing) and one small cube (underwear and socks) use space efficiently.

Where should the heaviest items go in a carry-on bag?

Place the heaviest items against the back panel of the bag — the side closest to your back when you carry it, or closest to the wheels if it is a rolling case. This keeps the bag's centre of gravity low and stable, reducing strain when lifting it into the overhead bin.

Should a laptop go in the main compartment or a dedicated sleeve?

Always use a dedicated laptop sleeve or compartment if your bag has one. A dedicated sleeve keeps the laptop flat (important for hard drives), provides padding, and means the laptop is accessible for security without fully opening the bag.

How to Organize a Carry-On Bag: Packing Order and Tips

Packing a carry-on is not just about fitting everything in — it is about being able to move through the airport efficiently and arrive at your destination with undamaged belongings. The single most useful concept is the access-order principle: pack in reverse order of need, so the first things you need are always on top or most reachable.

The Access-Order Principle

Think through your journey from home to hotel room:

At security: you need your toiletries bag and laptop out of your bag
During the flight: you may want your headphones, snacks, or an in-flight kit
On landing: you may need your phone charger quickly
At the hotel: everything else

The mistake most people make is packing in destination order — clothes and toiletries first, because that's what they think about first. This buries the items you need at security at the bottom of the bag.

Pack in the opposite order. Put destination items in first. Put security items in last.

The Full Packing Sequence

Step 1: One Clothing Layer on the Very Bottom

Before anything else, lay a flat layer of soft clothing — a t-shirt, a merino jumper, a pair of lightweight trousers — across the bottom of the main compartment. This acts as a buffer layer that protects the base of the bag and cushions anything packed above it.

This is especially useful if your bag is a soft-sided nylon type without a rigid base. It also works as impromptu padding if you are carrying breakable items.

Step 2: Packing Cubes with Clothing

Next in are packing cubes containing your clothing. For a 3–7 day trip in a 40-litre carry-on, a typical setup is:

One medium cube for tops (t-shirts, shirts, lightweight layers)
One medium cube for bottoms (trousers, shorts, a dress if applicable)
One small cube for underwear and socks

Roll clothing before placing it in cubes rather than folding flat. Rolling reduces creases and compresses the cube more efficiently. Compression cubes (with a second zip that squeezes the cube smaller) can reduce clothing volume by 30–40%.

Place the filled cubes in the main compartment with the heaviest cube at the back of the bag (against the back panel, closest to the wheels on a roller bag).

Step 3: Shoes

Shoes go in next if you are not wearing them. Use shoe bags or shower caps to contain dirt and protect clothing. Shoes sit in the gaps around and between packing cubes — don't waste the irregular spaces that cubes create.

Step 4: Tech Pouch in an Outer Pocket

All cables, chargers, adapters, and small electronics go in a single tech pouch. This single-pouch rule means you never search through the bag for a USB cable. The tech pouch goes in an outer zip pocket, not buried in the main compartment.

Contents of a typical travel tech pouch:

USB-C charging cable
Plug adapter if travelling internationally
Earphones (if not in the laptop sleeve)
Power bank
SD card reader (if applicable)
Short HDMI or display adapter if needed for work

Step 5: Laptop in the Dedicated Sleeve

If your bag has a dedicated laptop sleeve — typically a padded compartment at the back of the main compartment — use it. Place the laptop screen-face toward the padding, not toward the main compartment, to protect the display.

If your bag has no dedicated sleeve, use a neoprene laptop case and place it last into the main compartment, on top of the packing cubes. This makes it easy to pull out at security.

Keep your laptop charger in the tech pouch, not in the laptop sleeve — sleeve space is tight and mixing cables with the laptop creates a tangled unpacking experience every time.

Step 6: In-Flight Essentials in the Top Pocket

The small top or front pocket (if your bag has one) is for items you need during the flight:

Phone and earbuds
Neck pillow if you use one
Eye mask and earplugs
Book or e-reader
Light snack

These need to be accessible after you've put the bag in the overhead bin — so you take them out and keep them at your feet or in the seat pocket.

Step 7: Toiletries Bag in the Most Accessible Spot

Last in, and therefore on top: your clear 1-litre toiletries bag. At security, this is the first thing you pull out. It should be in the most accessible outer pocket or at the very top of the main compartment with nothing on top of it.

Never bury the toiletries bag. Every extra second you spend unpacking at the security tray creates delay for you and the queue behind you.

Weight Distribution

For rolling carry-on suitcases: heaviest items (shoes, tech, packing cubes with denim) should be packed closest to the wheels. When the bag stands upright, this keeps the weight low.

For backpack-style carry-ons: heaviest items go against the back panel (the panel closest to your back when wearing). This keeps the centre of gravity close to your spine and reduces shoulder strain.

For bags carried by a top handle: distribute weight evenly side-to-side to prevent the bag from tilting in your hand.
