Kinda funny was a couple of months ago when flying domestically in Argentina I could carry on bottles of water, or for that matter booze. My last name on the ticket was misspelled and didn't match my passport. No problem. Apparently one mistake was no problem, two was getting iffy, and on the third a supervisor might have to flip a coin. OTOH, no liquids over 100ml, even if purchased after security, were allowed on the international flight back to the US. Duty free was delivered at the gate so was okay.
