I will stick my hand up here.
I frequently pack wine and spirits in my hold luggage coming back from land vacations and in nearly 40 years of doing so - never suffered a breakage - touch wood. Why I pack them - easier than carrying them by hand.
Method - roll bottle in tshirts etc and wedge securely in the middle of the case.
I will not guarantee the method but it works for me.
PS i know a true story of how a French language teacher accompanying children on a school trip who used this method to smuggle champagne in the suitcases of the children for over 30 years.
