Carry-on or checked, packing cubes, the 3-1-1 liquids rule, documents, electronics and adapters, clothing by climate, and the mistakes that fill a bag for no reason. The complete method to pack once and never scramble at the airport again.

**Carry-on only is a decision, not a constraint.** A well-packed 40-liter bag covers trips of 7 to 14 days if you master the 3-3-3 rule (3 tops, 3 bottoms, 3 pairs of socks) and do laundry midway.
**The 3-1-1 liquids rule still applies in carry-on**: each container at **100 ml** maximum, all inside **one clear quart-sized plastic bag**, **one bag per passenger**. Bottles larger than 100 ml are rejected even when nearly empty.
**Packing cubes don't save space by magic** — they save time and order. The real volume gain comes from **rolling** garments, not folding. Compression cubes help with jackets.
**Documents are the only irreplaceable item.** A passport valid for **6 months beyond your return date**, digital photos of everything in the cloud, and a physical copy stored separately from the original.
**Electronics: pack fewer cables than you think you need.** One 65W GaN charger with multiple ports replaces three chargers. A universal adapter covers 150+ countries; a power bank up to **100 Wh** goes in carry-on, never checked.
