Everything you can't afford to lose or need in flight: passport and documents, medication, electronics and chargers, valuables, one change of clothes, a liquids bag under 100 ml, snacks, a refillable bottle, and comfort items (mask, earplugs, layer).
Must be in the cabin: passport/ID, boarding pass, medication (in original packaging), power banks and spare batteries, laptop and camera, keys, cash and cards, jewellery.
Smart to have: a change of clothes and underwear (in case checked bags are delayed), toiletries under 100 ml, a pen for arrival forms, snacks, an empty bottle, a light layer, earbuds, eye mask, earplugs, a portable charger.
Don’t bother: full-size toiletries, more than one book, a pillow the size of a suitcase.
Organise: one pouch for tech, one clear bag for liquids, one for documents — security is faster and nothing gets lost in the seat pocket.
