What is the liquid allowance on British Airways?

Each liquid must be in its own container of no more than 100ml (3.4oz). You need to put all items in a single, transparent, re-sealable plastic bag of up to 20 x 20cm (8 x 8in) with a total capacity of up to one litre (approx. one quart). You must be able to completely close the bag and fit it in your hand baggage.



In 2026, the liquid allowance for British Airways passengers varies significantly depending on the airport's security technology. At major UK hubs like Heathrow, Gatwick, and Birmingham, new CT scanners have officially "scrapped" the 100ml rule, allowing you to carry containers of up to 2 litres in your hand luggage without removing them from your bag. However, if you are flying from airports that have not yet fully rolled out this tech (such as Manchester or many international destinations), the traditional 100ml (3.4oz) rule still applies. In those cases, all liquids must fit into a single, transparent, quart-sized (20x20cm) resealable bag. Because of this "mixed" environment, the 2026 "pro-tip" is to always check the specific rules of your return airport; while you can take a large bottle of gin through Heathrow on the way out, you might be forced to discard it at a smaller European airport on the way back if they haven't upgraded their scanners yet.
