In Europe (did a lot of flying lately) the 100ml still stands for sanitizers. You can go over the 100ml only if you got a baby with you and they allow the water/milk for the baby.
The whole restriction on liquids is fairly ridiculous, and even more of a security theater than most of the other checks. And I think the security guards know it, and use any excuse to look the other way.
This exception makes the TSA's policy more pragmatic and reasonable.
The harm of denying a baby milk or formula is worse than the risk of terrorism in this case. Not to mention is that it lowers the incidence of crying babies on flight.
The same logic could be applied to hand sanitizer restrictions in a global pandemic. Allowing people to carry a larger size could save more lives than the risk it poses. This is especially true when shortages can make it difficult to buy a travel size.
Why would that be the case?
