Cabin baggage: the rules to know before you reach security

Cabin baggage rules vary from one airline to another, even on the same flight+hotel package: the allowed size and weight depend on the ticket, not the destination. The first thing to check is always the airline's own page linked from your booking confirmation, before you pack.

Liquids remain governed by a rule common to most European airports: containers of 100 ml or less, gathered in a single resealable one-litre transparent bag. Anything larger goes in the hold.

Lithium batteries (cameras, power banks, e-cigarettes) must travel in the cabin, never in the hold: this is a safety rule, not something left to the passenger's judgement. High-capacity power banks (above roughly 100 Wh) generally require the airline's prior approval.

On a one-way flight or a round trip with a low-cost carrier, the "free" cabin allowance is often limited to a single bag under the seat in front of you; a standard wheeled cabin case is then a paid extra. Checking this before departure avoids an unpleasant surprise at the check-in desk.

If in doubt about a specific airline, customer service remains reachable by WhatsApp or phone before departure to confirm the rules that apply to your ticket.
