What if I need more than 10 days of clothes?

Do laundry. Every hotel, hostel, and Airbnb has either a machine or a local sink. Packing for 10 days is sufficient for a 3-month trip if you wash your clothes once a week.

Does my personal item count toward the limit?

Yes. Your personal item should be a backpack that fits under the seat, holding your electronics and emergency kit. Keep your main carry-on overhead.

Mastering the One-Bag Carry-On Method

To fit everything in a carry-on, you must limit yourself to 10 days of clothing, prioritize technical fabrics, and use compression cubes to remove excess air. If it doesn't fit in a standard 22x14x9 inch bag, it doesn't go.

Adopt the 5-4-3-2-1 Rule. Pack 5 tops, 4 bottoms, 3 pairs of socks and underwear, 2 pairs of shoes (one worn, one packed), and 1 accessory (like a hat or belt). Stick to a cohesive color palette so everything matches.
Use Compression Packing Cubes. Fold clothes flat or use the Ranger Roll method, then place them into compression cubes. Zip the secondary zipper to squeeze out remaining air, reducing volume by up to 30%.
Wear Your Bulkiest Items. Always wear your heaviest coat, boots, and thickest sweater on the plane. This saves critical space and weight for your packed items.
Optimize Your Toiletries. Ditch full-sized liquids. Use solid versions of shampoo and deodorant, and store all liquids in a clear, quart-sized silicone pouch to move through security in under 60 seconds.
