In 2026, Ryanair’s policy regarding Ziploc bags is dictated primarily by the security regulations of the airports it serves rather than the airline's own baggage rules. For liquid transport in hand luggage, you are permitted one single transparent, resealable plastic bag per passenger. This bag must have a capacity of no more than 1 liter and typically measures around 20cm x 20cm (approx. 8 inches x 8 inches). All your liquid containers, each limited to 100ml (unless you are at an airport equipped with 2026-standard CT scanners that allow up to 2 liters), must fit comfortably inside this one bag, and the bag must be fully sealed. If you are carrying empty Ziploc bags for organization or snacks, there is no specific limit on the quantity, as long as they do not contain restricted liquids or gels. However, for the security screening process, only one "liquids bag" is allowed per person. At many UK and European hubs, security staff will provide these bags if you forget one, but bringing your own ensures you are packed to the correct dimensions before reaching the busy screening queues.
