Ended up checking a daypack with small bottles of liquids, which I would rather have carried aboard. Using LHR First Wing security, I watched an absurd display of the guy in front having every toiletry item removed and individually dissected, perhaps to determine the remaining liquid content? This while bags at Schipol and other advanced airports sail through without passengers needing to remove anything. The same is generally true in the U.S. Bags for tiny bottles of liquids haven’t been a thing for years.
