Another time I was running late for my flight and forgot to empty my 16oz water bottle. After my bag went through the scanner I realized my mistake and told the TSA agent about it. He uncapped the bottle, swirrled the water around, sniffed it, and then handed me back 16 ounces of water and said not to worry about it.
So yeah, I have minimal expectation TSA will catch this.
Now UK airport security might handle it. I've been specifically asked if my laptop has been damaged, is swelling or has been recently repaired. I assume if you answer yes to any of those questions your device is banned from flying.
I am not sure what changed because I haven't seen this before. Even modern airports like Changi (Singapore) required me to empty my bottle. If anyone knows what changed, always interesting to read!
Source: flew from Schiphol 3 times in the last few months.
If you are on about collecting fingerprints at immigration, the US does that, as do many other countries.
And you're indeed correct. And that must have been chilled for a long time to freeze that quantity. (Edited: thought you said 1.5l of alcohol)
I guess that means they at least looked at the X-Ray; it seems like a lot of the time they don't even bother to do that.
By contrast, when I was trying to board my plane in Tokyo to return to the US, I again forgot to empty my water bottle, and was already through the line. The woman just asked if she could dump it, and she did: they had special containers there for the express purpose of dumping people's disallowed liquids. Of course, American security can't be bothered to implement a common-sense measure like this.
But that one time I had a bottle of diet coke... That's when they get me.
Given the reactions to the Boeing news that I've heard, it would be surprising to me if people would risk jeopardising the safety of a flight to bring a personal item. However, people do remain people and act accordingly.
