What are the most important things to always have in your carry-on?

At minimum: passport/ID, phone and charger, any prescription medication, one change of clothes, and your most valuable electronics. These are items you cannot afford to lose if checked luggage is delayed or lost.

What should stay in your personal item vs carry-on bag?

Your personal item (under-seat bag) should hold items you need during the flight: phone, headphones, wallet, passport, neck pillow, eye mask, medication, and anything you'd want access to without getting into the overhead bin. Your carry-on is for the destination.

What liquids are allowed in a carry-on?

In most countries, liquids must be in containers of 100ml (3.4oz) or less and fit in a single clear 1-liter zip-lock bag. Exceptions include medication (must be declared), baby formula, breast milk, and some medically necessary liquids. The UK has maintained the 100ml rule post-Brexit.

Can I bring my laptop in my carry-on?

Yes. Laptops must be removed from your bag and placed in a separate security tray at most airports (TSA in the US requires this; EU airports typically require it as well). Pack your laptop in an easily accessible sleeve or pocket near the top of your bag.

How many days' worth of clothes fit in a carry-on?

With efficient packing — rolling clothes, using packing cubes, avoiding heavy fabrics — most people can fit 7 days of clothing in a 40–45 liter carry-on. The key constraints are bulky items like shoes (limit to 2 pairs) and jackets.

Ultimate Carry-On Packing Checklist (2026)

The difference between a well-packed carry-on and a chaotic one usually comes down to a checklist consulted before you zip it closed. This guide provides a complete, category-organized packing list for carry-on travel, along with guidance on what stays in your personal item for in-flight access.

How to Use This Checklist

The checklist is organized into two sections:

Carry-on bag (overhead) — items for your destination that you don't need during the flight
Personal item (under seat) — items you need during the flight and want within reach

On budget airlines where only one bag is free, everything on both lists needs to fit in a single bag. On most other carriers, you get both.

Documents & Travel Essentials

These are non-negotiable. Don't pack them in checked luggage — if your checked bag is delayed or lost, you need these with you.

Passport (valid for at least 6 months beyond travel dates)
Driver's license or national ID
Printed or downloaded boarding passes (airline app, PDF, or print)
Hotel confirmations / accommodation details (downloaded offline)
Travel insurance documents or app
Visas (printed or accessible in app)
Emergency contact information (written on paper as a backup)
Travel credit cards and some local cash
Frequent flyer membership card or app

Tip: Store everything on your phone as well as a cloud service you can access offline. Email yourself key confirmation numbers so you have a fallback.

Technology & Electronics

Battery bank rule: Portable batteries (power banks) are NOT permitted in checked baggage on most airlines worldwide. They must travel in your carry-on or personal item. Check the watt-hour limit: most airlines allow up to 100Wh per bank, some allow up to 160Wh with airline approval.

Toiletries & Health

Liquids (must comply with 100ml rule in most countries):

Travel toothbrush and toothpaste (≤100ml)
Deodorant (solid stick, or ≤100ml liquid)
Face wash or cleanser (≤100ml)
Shampoo and conditioner (travel size, or solid bars — bars skip the liquid rules)
Moisturizer and lip balm
Sunscreen (≤100ml; larger sizes can be checked or purchased at destination)
Clear 1-liter zip-lock bag for all liquids

Non-liquid toiletries (no restrictions):

Solid shampoo and conditioner bars (no liquid limit — highly recommended)
Solid facial cleanser bar
Safety razor (disposable or safety razor — not cartridge with blade exposed; check airline rules)
Tweezers (permitted in most countries but not all — check destination)
Nail clippers
Comb or brush

Health items:

Prescription medications (in original packaging; carry the prescription if controlled)
Over-the-counter pain relief (ibuprofen, paracetamol/acetaminophen)
Antihistamines
Motion sickness medication if needed
Band-aids and basic first aid
Hand sanitizer (≤100ml)
Vitamins or supplements

Clothing

The number of items depends on trip length and destination climate. Below is a standard 5–7 day template for a temperate climate:

Tops:

3–4 versatile tops (mix solid colors that layer and mix-match)
1 dressier top or blouse/shirt for an evening out
1 lightweight layer or cardigan

Bottoms:

2 pairs trousers or jeans (one casual, one smarter)
1 pair shorts or skirt (climate dependent)

Underwear & socks:

5–7 pairs underwear (lightweight; quick-dry fabric for sink-washing)
4–5 pairs socks (merino wool recommended for odor resistance and versatility)

Outerwear:

1 packable rain jacket or windbreaker (in its own stuff pocket)
Warm mid-layer if needed (packable down or fleece)

Shoes (maximum 3 pairs — wear the heaviest):

Everyday walking shoes (worn on plane)
Casual evening shoes (packed)
Optional: sandals, athletic shoes, or specialist footwear for specific activities

Packing technique: Roll tops and underwear. Use packing cubes for compression. Place shoes in shoe bags at the bottom/sides of the bag. Heaviest items (shoes, jeans) near the bag's wheeled end or back panel.

Comfort Items for the Journey

These are particularly important for long-haul flights but valuable on any journey:

Neck pillow (inflatable compresses to nothing; solid memory foam is bulky)
Sleep mask / eye mask
Earplugs (even with noise-canceling headphones, for sleeping)
Compression socks (DVT prevention on flights over 4 hours)
Lightweight scarf or shawl (doubles as blanket on cold aircraft)
Small snacks (granola bars, nuts — permitted in most carry-ons)
Reusable water bottle (empty at security; fill at airport fountain or buy airside)
Pen (for customs forms on international arrivals)
Reading material or entertainment

What Goes in Your Personal Item

Your personal item (the bag under the seat) is your in-flight office and emergency kit. Items here stay accessible during the entire flight without reaching overhead.

Always in the personal item:

Travel days especially:

One change of clothes (if checking nothing — insurance against spills or very long journeys)
Lip balm and facial mist (airplane cabins are extremely dry)
A good book or downloaded entertainment if not traveling with laptop

The "Never in Checked Luggage" Rule

Some items must always be in your carry-on regardless of whether you're also checking a bag:

Passport and ID
Prescription medications
Portable batteries / power banks (prohibited in hold by IATA regulation)
Laptop and irreplaceable electronics
Valuables (jewelry, cash, important documents)
Keys to your destination (if applicable)
Items you'd be stranded without if your checked bag were delayed 24–48 hours

Checked bags are delayed, misrouted, or lost every day. Everything above cannot wait 24 hours to be reunited with you.

What to Skip: Common Over-Packing Mistakes

Too many pairs of shoes. Three maximum. Each extra pair typically weighs 500g–1 kg and takes up 3–5 liters.

"Just in case" outfits. Pack outfits you'll actually wear. The "just in case" evening dress or fourth pair of jeans stays home.

Full-size toiletries. Hotels provide shampoo, conditioner, and soap in most cases. Solid bars bypass liquid rules and weigh less than bottles.

A hair dryer. Hotels have them. Even budget hotels.

Multiple books. One book + an e-reader with many books loaded is the carry-on solution.

Separate entertainment and comfort items you'll use once. Travel pillows are worth it. The dedicated foot hammock is not.

Packing Order: What Goes Where

Bottom of bag (or back panel on a backpack): Heavy items: shoes, laptop (in padded sleeve), portable battery

Middle: Packing cubes with clothing

Top (most accessible): Liquids bag, laptop if laptop needs to come out at security, rain jacket

External pockets: Snacks, pens, passport if using a backpack, items needed immediately on arrival

The Bottom Line

A well-organized carry-on checklist ensures you have what you need without lugging what you don't. The framework: documents and essential tech in your personal item at all times, clothing and toiletries in the overhead bag, and a strict maximum on shoes and "just in case" items. The most important single decision is your shoes — limit to three pairs, wear the heaviest, and half your packing battle is already won.
