Airlines Could Soon Lift 100-Milliliter Liquid Limit for Carry-On Bags

Advances in security scanning technology may lead to the end of restrictions on liquids in hand luggage, but no timeline has been confirmed.

The 100-milliliter liquid limit for carry-on luggage, in place since 2006, may soon be eliminated according to IATA's chief, Willie Walsh.
These restrictions were introduced to prevent the smuggling of explosives onto planes and are based on ICAO recommendations.
Modern scanner technology has advanced to a point where it can reliably detect dangerous materials, potentially making the restrictions unnecessary.
The decision to lift the liquid limit rests with individual governments, which initially implemented the rules based on ICAO guidelines.
While Walsh expressed optimism about the change, he did not provide a specific timeline for when the restrictions might be removed.
