The Packing Formula
Carry-On Only Travel

Die Goldene Regel

Alles auslegen. Haelfte entfernen. 7-Tage-Reise: 3-4 T-Shirts, 2 Hosen, 7 Unterwaesche, 2 Paar Schuhe. Alle 3-4 Tage waschen. Handgepaeck (7-10 kg) reicht fuer 90% aller Reisen bis 10 Tage. Ryanair/EasyJet: Handgepaeck-only spart 30-60 € pro Strecke.

Haeufig Vergessen

Powerbank. Medikamente. Passkopie im E-Mail. Steckdosenadapter. Plastikbeutel fuer Schmutzwaesche.

⚡ CalcWolf Insight

The biggest packing mistake: packing "just in case" items you never wear. Studies show travelers wear only 60-70% of what they pack. Before adding anything to your suitcase, ask: "Will I definitely wear/use this at least twice?" If not, leave it. You can buy almost anything at your destination if needed.
