Yes, airports still check liquids in 2026, but the process has become significantly faster and less restrictive at many major international hubs. The long-standing "100ml rule" is currently being phased out in several countries, most notably in the UK. As of 2026, airports like London Heathrow, Birmingham, and Edinburgh have officially scrapped the 100ml limit, allowing passengers to carry containers of up to 2 liters of liquids, pastes, and gels. This is thanks to new "Next Generation" CT scanners that provide a detailed 3D view of bag contents, eliminating the need to use clear plastic bags or remove liquids from luggage. However, many airports globally—including most in the US and smaller regional hubs in Europe—still enforce the traditional 3.4 oz (100ml) limit and require the use of a quart-sized bag. If you are traveling through multiple airports on a single trip, it is vital to check the rules for each segment, as you may be allowed 2 liters at your departure but still have to toss anything over 100ml at a connection point.
