7-Day Carry-On Packing List: How to Pack for a Week
Share
Travelling carry-on only for a week is completely achievable with the right 55cm suitcase and a structured packing plan.
No checked baggage. No carousel waits. No lost luggage.
This 7-day carry-on packing list shows you exactly what to pack, how to fit it into one cabin-size suitcase, and how to stay within airline limits.
Why Travel Carry-On Only?
More Australian travellers are choosing carry-on only travel for good reason.
• Faster airport exits
• No checked baggage fees
• Reduced lost luggage risk
• Easier movement between destinations
• Less lifting and hauling
When your luggage stays with you, travel becomes simpler and more efficient.
Step 1: Choose the Right 55cm Carry-On Suitcase
If you want to pack carry-on only for seven days, your suitcase matters.
Not sure which case to choose? Read our guide to the best carry-on luggage in Australia to compare lightweight 55cm spinner suitcases, softside cabin cases and family-friendly options.
Why 55cm Is the Ideal Cabin Size
A 55cm carry-on suitcase is the standard cabin size across most full-service airlines in Australia and internationally.
It fits in overhead lockers while still offering enough capacity for a structured 7-day carry-on packing list.

What Is a Spinner Suitcase?
You will often see the term “spinner” when shopping for carry-on luggage.
A spinner suitcase has four wheels that rotate 360 degrees. This allows you to:
• Push it upright beside you
• Glide it through airports without tilting
• Move it easily in any direction
Unlike older two-wheel suitcases that must be tilted and pulled, a spinner carry-on rolls smoothly on all four wheels. This reduces strain on your arm and shoulder, especially in large airports.
For most travellers, a lightweight 55cm spinner suitcase offers the easiest airport experience.
How Much Should a Carry-On Suitcase Weigh?
Most airlines allow between 7kg and 10kg for cabin baggage.
A lightweight carry-on suitcase, ideally under 3kg empty, gives you more flexibility within those limits.
Look for:
• Lightweight polycarbonate or polypropylene construction
• Smooth double spinner wheels
• Internal compression straps
• Expandable options for return travel
The lighter the case, the more you can pack.
The Complete 7-Day Carry-On Packing List
If you are searching for what to pack for a week in a carry-on, this formula works consistently.
Clothing Essentials
3 tops in neutral, interchangeable colours
2 bottoms, one casual and one elevated
1 lightweight layer or travel hoodie
1 sleepwear set
4 underwear
2 bras
3 pairs of socks
1 swimsuit
This creates multiple outfit combinations without overpacking. Every top should work with every bottom.
That is the foundation of one bag travel.
Shoes for Carry-On Travel
1 pair of trainers or walking shoes
1 pair of flats, sandals or dress shoes
1 pair of lightweight flip flops
Wear your bulkiest pair on the plane. This saves space and helps you stay within airline weight limits.
Two or three versatile pairs are more than enough for a seven-day carry-on trip.

What to Wear on the Plane
Your travel outfit is part of your packing strategy.
Wear your heaviest shoes.
Wear your bulkiest layer.
Choose pieces that can be reused during your trip.
A functional travel layer like the Avionlux Dream Travel Hoodie is designed for travel.
It provides comfort on long flights, features a built-in eye mask, and includes hidden pockets for passport, cards and essentials.
How to Fit 7 Days Into One Carry-On Suitcase
Packing technique is just as important as your packing list. The right method can easily create extra space inside a 55cm carry-on suitcase.
Roll Soft Items
Roll T-shirts, knitwear and casual pieces to maximise space and reduce creasing.
Place structured garments flat at the base of the suitcase.
Layer and Fold Structured Pieces
For dresses, blazers or tailored garments, lay them flat on top of one another and fold them together as one. Folding multiple layers at once reduces shifting and helps minimise wrinkles.
Position these folded layers at the base of your carry-on.
Pack Vertically
Stand rolled clothing upright rather than stacking it flat.
This allows you to see everything instantly and prevents overpacking.
Use Packing Cubes
Packing cubes help:
Compress clothing
Separate outfits
Stay organised during your trip
They significantly improve organisation inside a carry-on suitcase.
Wear Bulky Items Instead of Packing Them
Do not pack heavy jackets, thick hoodies or boots if you can wear them.
This protects your available cabin weight and maximises internal space.
