Passengers who start their journey at an EU airport only have liquids in their possession in compliance with the regulations. As a result, they can also take these liquids on board their connecting flights.
However, passengers catching connecting flights after starting their journey at a non-EU airport are themselves responsible for ensuring that any liquids they are carrying in their hand luggage are in containers no larger than 100 milliliters and packed in a plastic bag in compliance with the regulations (with a volume not exceeding 1 liter).
Duty free items purchased at non-EU airports or on flights with non-EU airlines cannot be taken aboard connecting flights departing from EU airports.
Can passengers whose flights originate outside the EU and change planes at an airport within the EU transport liquids in their hand luggage?
Liquids carried on flights outside the EU must be packed in the permitted quantities in a transparent, re-sealable plastic bag (max. volume: 1 liter) when transferring at an airport within the EU. In case of non-compliance, the liquids cannot be taken on board.
Duty-free liquids purchased at any airport or on board a flight are allowed in hand luggage as long as they are sealed in a tamper-evident security bag and are screened using the special explosives-detection technology. This technology is also used to screen liquid medicines and liquid foods.
