I haven't had anything stolen by TSA, and a bottle of wine is inexpesnive enough that I wouldn't swet it any more than I would regarding a jacket or some shoes or many other things I'd pack. Breakage is a greater risk, but you can largely (not completely) avoid that risk by packing it well. I've done it, with hard liquor, more than once, with no breakage or theft problem. To pay a higher price, and with a smaller selection, in the airport or on board the ship because of the small chance of the bottle in checked baggage going missing just doesn't make sense to me. Sort of like insurance costing nearly as much as a car. There may well be wine available in duty free sales aboard the flight, but, again, a higher price and, even more certainly, smaller selection (and you don't know if they'd have Chardonnay; you could contact your airline to see what they do sell) than at a liquor store outside the airport.
