Last Easter I did find a vodka on an Aluminum (sp?) bottle and I decided to buy it. I was asked where I was flying (it was a very short domestic sector) but I did insist on doing a full packaging. I told them we might diverting and I did not want to argue with the security staff. Talk about being pessimistic.
They did comply no problem and as a matter of fact when I buy a liquid I always request a sealed bag.
