Carry-on liquids: the 100 ml rule in 2026

The 100 ml limit still applies at most airports. A growing number with new CT scanners allow more, but the rules differ by airport and even by terminal.

The standard rule

Liquids, gels, aerosols and pastes in containers of up to 100 ml each, all fitting in one resealable 1-litre bag, one bag per passenger. Larger containers go in checked luggage, even if nearly empty. Medicines and baby food are exempt but may be inspected.

Where it is relaxed

Airports that have installed CT security scanners can allow containers of up to 2 litres and let you keep liquids and laptops in the bag. Several UK, EU and Asian airports have switched, but others reverted after EU reviews, and your return airport may still use the old rule.

Pack as if the 100 ml rule applies on every leg unless both airports on your itinerary confirm otherwise on their official sites.

Common mistakes

Duty-free liquids bought before a connection: keep them sealed in the tamper-evident bag with the receipt.
Solid alternatives (shampoo bars, toothpaste tablets) are not liquids and have no limit.
Power banks must be in the cabin bag, never checked, usually up to 100 Wh without approval.
