Bringing Frozen Liquids through Airport Security
Gizmodo reports that UK airport security confiscates frozen liquids:
“He told me that it wasn’t allowed so I asked under what grounds, given it is not a liquid. When he said I couldn’t take it I asked if he knew that for sure or just assumed. He grabbed his supervisor and the supervisor told me that ‘the government does not classify that as a solid’. I decided to leave it at that point. I expect they’re probably wrong to take it from me. They’d probably not seen it before, didn’t know the rules, and being a bit of an eccentric request, decided to act on the side of caution. They didn’t spend the time to look it up.”
As it happens, I have a comparable recent experience. Last week, I tried to bring through a small cooler containing, among other things, a bag of ice. I expected to have to dump the ice at the security checkpoint and refill it inside the airport, but the TSA official looked at it and let it through. Turns out that frozen liquids are fine. I confirmed this with TSA officials at two other airports this week.
One of the TSA officials even told me that what he was officially told is that liquid explosives don’t freeze.
So there you go. The US policy is more sensible. And anyone landing in the UK from the US will have to go through security before any onward flight, so there’s no chance at flouting the UK rules that way.
And while we’re on the general subject, I am continually amazed by how lax the liquid rules are here in the US. Yesterday I went through airport security at SFO with an opened 5-ounce bottle of hot sauce in my carry-on. The screener flagged it; it was obvious on the x-ray. Another screener searched my bag, found it and looked at it, and then let me keep it.
And, in general, I never bother taking my liquids out of my suitcase anymore. I don’t have to when I am in the PreCheck lane, but no one seems to care in the regular lane either. It is different in the UK.
EDITED TO ADD (10/13): According to a 2009 TSA blog post, frozen ice (not semi-melted) is allowed.
