What if my kids can't carry their own bags?

If they are too small, you should consolidate everything into two adult-sized 40L bags. If you cannot manage the gear, you are packing too much.

How do I handle bulky winter gear?

Wear your heaviest coat and fleece on the plane. Use vacuum-compression bags only for the return trip if you plan on buying souvenirs.

Packing Carry-On Luggage for a European Family Trip

Stick to a strict one-bag-per-person policy using compression cubes to maximize space. Plan for a 7-day wardrobe that you can wash mid-trip to avoid checked luggage fees and the risk of lost bags on tight European connections.

Select the right bags. Every family member needs a 40L travel backpack that meets international carry-on dimensions (typically 55cm x 40cm x 20cm). Avoid suitcases with wheels if you are traveling to cities with cobblestone streets.
Use a modular packing system. Use packing cubes for every family member. Assign a specific color cube to each person so you can identify clothes instantly inside shared luggage or tight overhead bins.
Limit the footwear. Wear your bulkiest shoes on the plane. Pack exactly one extra pair of lightweight, versatile sneakers per person. If they can't be worn for 15,000 steps of sightseeing, leave them at home.
Consolidate liquids. Use solid toiletries like shampoo bars and toothpaste tabs. Put all liquid essentials into one communal quart-sized bag per adult to streamline security checks.
Plan for laundry. Pack enough undergarments for 8 days and outer layers for 4 days. Plan to use a local laundromat (lavanderia/laverie) halfway through your trip.
