Would like to take a friend in Miami a dozen bottles of fine Australian white wine as gift next wek. Plan to leave it in the winery box with bubble wrap around each bottle. I hope that UA will accept it as checked baggage like that, if we accept the standard "Fragile" disclaimer etc?

I do not have a US Customs form with me, but recall there is a fixed printed limit on how much wine is allowed. Does anyone know for sure what that is? Two passengers travelling together, so 12 x 750mm = 9 litres total, so that would be 4.5 litres each. Hopefully in the Festive spirit mood, they may not get too bothered by this - or maybe they are strict? Appreciate any input.
