Well, what are you supposed to do with all of that duty free liquor you just bought. If you are on a long flight and want a little extra tipsy to help you relax, think of those old wooden kitchen spoons. Bring one. Remove the wrapper from the wine bottle and gently force the cork down into the bottle. You may have to share the contents with fellow people becuase there will be no resealing the bottle. I have also done this with an ink pen. If you are on a non-us carrier they may have a corkscrew on board. Where there is a will there is a way. Good luck!
