I have flown to and from Florida, Canada, Milwaukee, Denver, France, Italy, St. Thomas, Bermuda...with Wine, Grand Marnier...I simply put it in my carry-on and took it on the plane with me. As long as you don't drink it while you're on the plane you should be fine. Even though before 9/11, I always waited for the stewardesses to finish their Isle walk, then pulled out the bottle put it in the magazine seat pouch in front of me and took a few occasional sips.
Those were the good old Jet years.
Good Luck All,
Joe
P.S.
On our way to Denver, my friend brought a 6 pack of Bud in a collapsible cooler and drank it during the flight.
I would NOT recommend doing that today.
