Carry-On Essentials Checklist for a One-Week Trip

Travelling with only a carry-on saves time at the airport and avoids lost luggage. The trick is a short, repeatable checklist. Use this one as a starting point and adjust for your destination.

The bag itself

Airline carry-on size rules differ, so always check your airline's current limits before buying a bag. A soft-sided case with a flexible shape is usually easier to fit in overhead bins.

Clothing formula

For one week, plan for about four tops, two bottoms, one layer, sleepwear and underwear for each day, plus one outfit you wear on the plane. Pick colours that mix and match.

Tech and documents

Toiletries

Liquids in carry-on bags are limited by security rules that vary by country, commonly 100 ml containers in one clear bag. Check the rules for your airports. Solid shampoo, toothpaste tablets and refillable travel bottles help.

Small comfort items
