Last trip to Italy I used a 12 bottle styrofoam/cardboard box successfully.The problem was it was hard to lug around escecially Venice. My solution for this trip(Sept 26-October 11) is I bought a large suitcase at luggage for less in La($70),It is exaclty the size of the styrofoam stackable wine containers available at LA wine company. I will then fill the remaining spaces with foam (bought at a local foam store believe it or not) In this way I can get a highly portable(wheels) way to carry 18 bottles of wine and still be under the weight limit of 70 lbs for Alitalia, including the weight of the suitcase(10lbs).I will check the suitcase empty except for the foam and styrofoam on the way out,also taking a hard sided case empty on the way out for Ceramics,art or whatever else we buy,Maybe I can jam a few bottles in there as well! I also plan on carrying on 6 bottles but once was stopped by KLM because the carry on limit is 14 lbs(6 bottles of wine weighs about 20lbs plus) Robert
