Carry-on Only: Master International Packing
To travel internationally with only a carry-on, you must limit yourself to 10 kilograms total and stick to a strict 5-4-3-2-1 clothing system. Focus on modular, quick-dry layers that serve multiple purposes to avoid exceeding airline size restrictions.
- Select the right bag. Use a 35L to 40L backpack with compression straps. Ensure dimensions do not exceed 55cm x 40cm x 20cm, which is the standard limit for most international carriers like Lufthansa or Emirates.
- Execute the 5-4-3-2-1 rule. Pack 5 tops, 4 bottoms (including what you wear), 3 pairs of socks/underwear, 2 pairs of shoes (one on your feet, one in the bag), and 1 versatile jacket. Choose fabrics like Merino wool or synthetic blends that resist odors.
- Maximize liquid compliance. Transfer all toiletries into 100ml silicone squeeze tubes. Keep them in a single, clear, quart-sized TSA-approved bag to move through security checkpoints in under 60 seconds.
- Use compression packing cubes. Roll your clothes tightly and secure them in compression cubes. This reduces volume by up to 30% and keeps your bag organized so you don't have to dump your belongings at customs.
- What if my bag is slightly over the weight limit?
- Wear your heaviest items—boots and a jacket—onto the plane. Once you are through the gate, you can stow them in your bag if space allows.
- How do I handle laundry?
- Plan to wash your clothes in a sink using a travel laundry detergent sheet every 5-7 days. Most hostels and hotels provide coin-operated machines if you prefer a full wash.
