Best way to pack these 6 bottles? If I bring them to the airport, will UA wrap them in something? Should I just wrap them myself in sweaters and put them in my suitcase?

I have a box that the wine came in, but it's in awful condition - I could use that as my second carry on, will UA accept it and will they handle it with care?

TIA

Sorry if there is already a thread on here which discusses this, i tried searching.
