At main Italian airports, perfume and large bottles of water, wine, and olive oil will be permitted in carry-on luggage without the need to display them. In addition to portable devices (such as tablets, laptops, and smartphones), liquids will be permitted in carriages, no longer subject to the 100 milliliter limit. When? Possibly as early as late July or early August, though sources cited by Corriere della Sera say the timeline is still under discussion. The procedures implemented after September 11, 2001 continue to have an impact on airport security checkpoints, which include metal detectors and scanners. Additionally, in 2006, a limitation on bringing liquid containers larger than 100 milliliters in carry-on bags was implemented. During the pandemic, airports began to install equipment capable of performing a genuine CT scan of passengers' personal goods, with Milan being one of the first in Europe. Software that immediately identifies explosives and presents high-resolution, three-dimensional images of luggage has rendered "traditional" liquids—beginning with wine—less hazardous.
