Carry-On Packing Guide

The Liquid Rule (100ml / 3-1-1)

The most important carry-on rule: all liquids, gels, pastes, and aerosols must be in containers of 100ml (3.4 oz) or less. All containers must fit inside one clear resealable 1-litre plastic bag (roughly 20 × 20 cm). One bag per passenger. Applies to toothpaste, shampoo, sunscreen, lip gloss, and gel-like foods.

• Exempt: Baby formula, breast milk, and prescribed liquid medication with documentation.
• Oversized containers: Even a mostly-empty 500ml bottle doesn't comply — transfer to a travel-size container.

Electronics

Laptops and tablets must be removed from your bag and placed flat in a separate tray at security. Power banks are only allowed in carry-on luggage — they're prohibited in checked bags due to fire risk.

• Power banks: Up to 100Wh without approval; 100–160Wh requires airline permission.
• Chargers: Carry a universal adapter for international travel and a short USB cable for in-seat ports.
• Headphones: Pack noise-canceling headphones accessibly — they transform a long flight.

Prohibited Items

• Always banned in carry-on: Knives with blades over 6cm, scissors over 6cm, any firearm or replica, heavy tools over 7 inches (18cm).
• Checked bag only: Full-size liquids (over 100ml), sharp tools, certain sports equipment.
• Allowed: Safety razors, cartridge razors, one disposable lighter (in pocket in the US, not in the bag).

Essentials Checklist

A well-packed carry-on covers you if your checked bag is delayed. Prioritize valuables and items you can't easily replace at your destination.

• Documents: Passport, boarding pass, visa, hotel confirmation, travel insurance.
• Medications: All prescriptions in original packaging, plus a few days' extra supply.
• Electronics: Phone, charger, power bank, headphones.
• Comfort: Travel pillow, eye mask, earplugs, a light layer, refillable water bottle (empty through security).
• Spare clothes: One change in case your checked bag is delayed.

Airline Size Limits

Every airline sets maximum carry-on dimensions. Exceed them and you may be forced to gate-check your bag. The most common limit is approximately 55 × 40 × 20 cm (22 × 16 × 8 inches). Budget airlines are often stricter.

• Measure with wheels and handles extended: That's how screeners measure.
• Personal item: Most airlines also allow a smaller bag under the seat — typically 35 × 25 × 20 cm.

Pro Packing Tips

• Roll clothes: Saves space and reduces wrinkles compared to folding.
• Top-load liquids: Keep the liquids bag accessible for quick removal at security.
• Use packing cubes: Compress clothing and make finding items fast.
• Wear your heaviest items: Heavy shoes and jacket on your body, not in the bag.
• Morning final check: Pack the night before, then re-check for overnight items (charger, toiletries).
