Does 100ml rule still apply?

We recommend packing all liquids, gels, and aerosols that are over 3.4 oz or 100 ml in your checked baggage, even if they are in a secure, tamper-evident bag. Liquids more than 3.4 oz or 100 ml not in a secure, tamper-evident bag must be packed in checked baggage.



In 2026, the "100ml liquid rule" is in a confusing transition period. At major hubs equipped with next-generation CT scanners, such as London Heathrow, Dublin, and several airports in Italy and Germany, the rule has been effectively scrapped. In these "smart lanes," you can carry up to two liters of liquid per container and keep them inside your bag. However, many airports (including Brussels and several smaller U.S. and Asian terminals) have not yet completed their equipment upgrades and still strictly enforce the 100ml limit. This creates a "patchwork" experience: you might be able to bring a full-size shampoo on your outbound flight but have it confiscated on your return. It is a peer-to-peer "safety essential" for 2026 to check the specific security policy of every airport in your itinerary; unless the airport explicitly states they have "New Security Technology," you should stick to the 100ml travel-size bottles to avoid losing your toiletries.
