What this means at London City Airport
- Airport states on its security page banner: 'Speed through security: leave your liquids in your bag, and please make sure they are 100ml or less.'
- plastic_bag_required is null: the airport's page does not mention a clear resealable bag either way.
- laptops_in_bag_allowed is null: the page lists laptops as allowed in hand baggage but does not say whether they must be removed at the screening point.
- The airport's 2023 press release titled 'New scanners bring end to hand luggage restrictions and 100ml liquid limit' now carries the note 'Redacted on 31.07.2025' and redirects to the current Security & Baggage page.
- Essential liquid medicines: 'Yes, if under 100ml. If over 100ml you must provide the relevant prescription and/or specialist letter of confirmation.'
- Liquid-type foods are listed as allowed in hand baggage only 'up to 100ml' (e.g. cranberry sauce, clotted cream, pate).
- Baby milk and food: CAA regulations allow enough for the journey; proof of onward travel gets a larger allowance.
- Thermos or metal flasks are only allowed empty.
