When returning from Jamaica, we connect in Atlanta. I have seen firsthand Rum Cream being confiscated even in the duty free packaging. Reason....it is not a clear liquid and therefore not allowed as carry on in Atlanta. We always re pack ours in our checked bags.
We do declare at Customs as we are clearly holding the bag, LOL! Pay particular attention to the 2nd sentence...
The Transportation Security Administration (TSA) limits carry-on liquids to 3.4 ounces (100 ml), unless you purchased alcohol at a duty-free shop at the airport after clearing security.
However, if you have a connecting flight within the U.S. and go through security again, then that bottle of alcohol you were initially allowed to carry on would have to be checked. To avoid this conundrum, wait until the last leg of a flight to buy duty-free alcohol.
