It is no longer possible to transport a treasured bottle of wine, or a special bottle of olive oil, in your carry on luggage when traveling on a commercial airliner. All liquids need to go into checked luggage.
When it comes to that special bottle… the one you are bringing along as a gift, the bottle you bought in that little off the beaten path winery on your vacation, your favorite vintage that you don’t want to be without….. you need to check it, but you REALLY want to keep it safe.
Don’t count on your socks to prevent breakage. These specially designed containers will insure that your bottles arrive in good condition (and that there are no unfortunate incidents in your socks).
