London Stansted Airport (STN)

Stansted Airport liquid rules

Stansted allows liquids in containers of 100ml or less. Thanks to the new scanners, you can leave liquids and electronics in your bag. If you’ve decanted anything into your own bottles, they need their capacity printed on them.

Faster through security, same 100ml limit

The new scanners change how you’re screened, not what you can carry. You no longer unpack your liquids or laptop, but each container still has to be 100ml or smaller. Anything bigger belongs in checked baggage.

Small cabin bag, small bottles

If you’re only taking a free under-seat bag — for example Ryanair’s or Wizz Air’s — space and the 100ml limit both push you towards travel-size toiletries. Buy travel bottles with the size printed on on Amazon UK (opens in a new tab) (paid link), or check your own containers are marked.

Exemptions

London Stansted Airport says the normal exemptions apply. Under GOV.UK rules those are:

Liquid medicine in a container over 100ml needs proof it is prescribed to you, such as a letter from your doctor or a copy of your prescription.

Container size

Use the size printed on the container — not how much is left inside.

Not stated by Stansted

Stansted’s page doesn’t say whether you need a clear plastic bag or whether metal drinks bottles must be empty. Follow the instructions at your security lane on the day.
