Packing for two weeks in a carry-on sounds impossible — until you try it. With the right gear and a smart packing strategy, most travellers can comfortably fit two weeks of clothing and essentials into a 40–45L carry-on bag. Here's exactly how to do it.
Why Pack Carry-On Only?
- No checked baggage fees (saves $30–$100+ per flight)
- No waiting at baggage claim
- No risk of lost luggage
- More flexibility to change flights or airlines
- Faster through airports overall
Step 1: Choose the Right Bag
For a 2-week carry-on trip, you need a bag that maximises every centimetre. The best options are:
- Carry-on suitcase (40–45L) — Structured, easy to pack, and rolls smoothly through airports. Best for city trips and business travel.
- Carry-on backpack (40–45L) — More flexible for mixed travel (cities + outdoor). Easier on uneven terrain and public transport.
Either way, make sure your bag fits within 56 x 36 x 23cm and weighs under 7kg when packed — the standard Australian domestic airline limit. Use a luggage scale at home to check before you leave.
Step 2: Use Packing Cubes
Packing cubes are the single biggest game-changer for carry-on travel. They compress your clothing, keep categories separate, and let you find things instantly without unpacking everything.
A typical setup for a 2-week trip:
- Large cube — tops and t-shirts (roll, don't fold)
- Medium cube — bottoms (pants, shorts, skirts)
- Small cube — underwear and socks
- Compression cube — bulkier items like a light jacket or jumper
Step 3: The Capsule Wardrobe Approach
The key to 2 weeks in a carry-on is choosing versatile, mix-and-match pieces rather than packing an outfit for every day. Aim for:
- 5–7 tops (mix of casual and smart-casual)
- 3 bottoms (2 pants/shorts + 1 versatile option)
- 1 light jacket or layer
- 7 pairs of underwear (plan to do laundry once)
- 3–4 pairs of socks
- 2 pairs of shoes (wear the bulkier pair on the plane)
Choose fabrics that are lightweight, wrinkle-resistant, and quick-drying. Merino wool is excellent for travel — it's odour-resistant and can be worn multiple times between washes.
Step 4: Manage Your Toiletries
Liquids are the biggest challenge for carry-on travel. CASA (Australia's aviation authority) requires all liquids, aerosols, and gels to be in containers of 100ml or less, carried in a single 1-litre clear resealable bag.
Tips to manage toiletries:
- Use a compact toiletry bag that fits neatly in your carry-on
- Decant products into travel-size containers rather than bringing full-size bottles
- Buy toiletries at your destination for longer trips
- Solid toiletries (shampoo bars, solid deodorant) bypass the liquids rule entirely
Step 5: Pack Your Tech Smart
Tech accessories add up quickly. Keep them organised and accessible:
- Travel adapter — essential for international travel; pack in your personal item for easy access
- Power bank — must travel in carry-on (not checked baggage) per airline rules
- Cable organiser — keeps cords from tangling and easy to find at security
- Laptop/tablet — pack in a sleeve in your personal item for quick removal at security
Step 6: Security and Valuables
Keep your valuables secure throughout your trip:
- RFID-blocking wallet — protects your cards and passport chip from digital theft in crowded areas
- Travel neck pouch — hidden under clothing for passport and emergency cash
- TSA lock — secure your bag zippers, especially in shared accommodation

Frequently Asked Questions
Can you really pack for 2 weeks in a carry-on?
